Wireless Bluetooth Ergonomic Trackball Mouse with RGB Backlight

As a first-time user of a trackball mouse, I was skeptical about its functionality compared to a regular mouse. There's a bit of a learning curve, but the comfort it offers is superior. The design feels more natural in the hand, as if it's tailored to work with your hand's shape. It's noticeably heavier than my previous, smaller mouse, but that's a minor adjustment.

This ergonomic trackball mouse is a gem, especially for someone like me who uses multiple laptops. The ease of switching devices with just a button touch is fantastic. The only improvement I'd suggest is relocating the buttons to the top or side instead of underneath. Nonetheless, it remains an excellent piece of equipment.

I really enjoy using this ergonomic trackball mouse. It's surprisingly easy to get accustomed to, and the battery life is commendable, lasting several days before needing a recharge. I find myself wishing I had made this purchase sooner.

This mouse has surpassed my expectations in every way. It's an amazing device that I use for 10-15 hours daily across various computers and laptops. Perfect for my workflow, it allows me to scroll through documents and webpages with ease and high precision.

The ergonomic trackball mouse works quite well overall. However, it's not entirely smooth; occasionally, the ball sticks a bit. This isn't a major issue for me, but for those needing flawless operation for tasks like design work, it could be a point of frustration.

Deciding to try out a trackball, I found this model to be excellent! It can sync with three different computers, is wireless and rechargeable, comfortable to use, and has a terrific side scroll wheel. Overall, it's a great addition to my desktop setup.

This is a very solid trackball with a no-slip base. Its ergonomic contoured shape fits my adult hand well, and the trackball action is very smooth. I haven't connected it to another PC or device, but the support for more than one connection is a great feature.

The ProtoArc Wireless Bluetooth Trackball Mouse, EM03 Ergonomic RGB Rollerball Mouse, has an excellent feel. The hand position is more comfortable, and the trackball feature improves operation as I don't have to move the mouse around. The ability to set up connections with three devices is a nice feature.

I've been a fan of using trackball mice for a few years now, starting with the Deft Pro and then the Huge. This new trackball is comparable right out of the box. Although I've modified my Elecom trackballs and still prefer them, this new one offers excellent value. Interestingly, the ball is the same size as the Deft Pro ball, so they are interchangeable, which is pretty cool.

Working from home, I struggled with using a trackpad all day, which led me to try this ergonomic trackball mouse. It resolved my issues of hand discomfort caused by regular mice. It's comfortable for extended use and doesn't cause any hand pain. I appreciate its wireless connectivity, easy setup, excellent battery life, and well-positioned scroll wheel. I'm really happy with this mouse.

I purchased this trackball as a replacement for an older model that had reached the end of its lifespan, and I'm quite impressed with it. Although I usually prefer a thumb-operated trackball, I've adapted to this forefinger-operated model and it works great.

For those who prefer using a trackball, this one is worth trying. It's responsive, comfortable to use, and even looks good on the desk. It fits my hand well (I wear a size L glove), though it might be less comfortable for those with very small or very large hands. Overall, I find it very comfortable.

I use this trackball for a computer that doesn't have much desk space, as it's a server. It's great to have this trackball instead of a regular mouse, which would require more space. The build quality is good, and it offers the choice of using a USB dongle or Bluetooth, which I really like.

This trackball is incredibly easy to use and extremely ergonomic, making it a pleasure to operate.

In terms of price, this is the best trackball mouse available. The build quality and design are excellent.

For a few years now, it's been challenging to find a good index-operated trackball. It's a relief to finally find one that works well and is reasonably priced.

This trackball is exceptional. The ball tracks very smoothly, and the shape is comfortable in the hand. The ability to pair with two different devices over Bluetooth and a third via the RF dongle offers great connectivity options. The RGB ring around the ball is a stylish addition.

I love this trackball. Among the many I've used, this is the first that fits my hand correctly since the Microsoft Explorer Trackball. Its design allows me to control the cursor with my three middle fingers, which is a huge plus for me.

After using this mouse for about a month, I am very satisfied with its performance. It features an internal battery for wireless use, though I usually keep it connected. The ball movement is smooth and precise. It connects wirelessly via Bluetooth, so no separate dongle is needed. The USB-C connection for charging is convenient, as it matches most newer phone chargers. The mouse fits my hand well and is very comfortable for extended use.

This mouse has been a game-changer for me, especially in my non-ergonomically set up workspace. It significantly helps in reducing my shoulder pain.

This mouse is fantastic, easy to use, and comfortable, preventing hand fatigue. I absolutely love using it.

The variety of connection options is impressive, including two different Bluetooth modes and a wireless USB. For KVM users, the wireless USB is a seamless choice. It plugs into the KVM slot and switches effortlessly, unlike Bluetooth connections which can be problematic. The ergonomic design is excellent, with a ball that rolls smoothly, a comfortable size, and well-placed buttons of the right size.

I absolutely love this mouse! After sustaining a hand injury, I decided to upgrade my mouse, and I'm thrilled with the result. The smooth operation, quiet buttons, and attractive design with cool lighting effects make it a joy to use. I'm very happy with this purchase.

As a longtime user of trackballs, especially the Logitech Marblemouse USB, this trackball stands out as the best I've ever used. Unlike others, it excels in fingertip control rather than thumb-ball control. The rolling action is both excellent and precise. I appreciate that it comes with a built-in 2.4 GHz adapter and also offers Bluetooth connectivity. Additionally, the smooth scrolling feature is a significant upgrade from the Marblemouse. Overall, I am extremely satisfied with this trackball.

The only significant flaw of this mouse is the high sensitivity of the left and right buttons, which can lead to accidental presses.

Although it takes some time to get accustomed to, this trackball is particularly useful for programming tasks.

I've been using Logitech and Kensington trackballs for as long as they've been around. Due to a past thumb injury, I can't use thumb-driven trackballs. Deciding to try this new model, I was not disappointed. It's a bit larger than I expected but has a great ergonomic feel and smooth action. It's just heavy enough to be stable without being inconvenient. I use it alongside a Space Mouse and an Intuos tablet for graphics work, and it's a great addition for anyone who loves trackballs.

After accidentally spilling water on my previous trackball mouse and rendering it unusable, I found this one as a replacement. Before purchasing, I was impressed by a video review highlighting its wrist-friendly design. This mouse contours better to my wrist and hand compared to my old one. It's perfect for someone with small hands like mine. I highly recommend this mouse to anyone with Carpal Tunnel Syndrome or similar hand issues.

Having used trackballs for years, this one is by far the best I've ever purchased. I've already ordered two more. Its operation is diamond smooth and flawless, making it the best trackball I've ever used.

Having a large collection of trackballs, I used to switch them out frequently due to declining comfort. However, this trackball has changed that. It doesn't try to reinvent the wheel with inferior designs; instead, it's a direct copy of the classic Microsoft Trackball Explorer, which is arguably the most comfortable design ever made. I don't see myself using any other trackball design. Despite its price, this trackball exceeds expectations in quality, especially the scroll wheel, which is often a weak point in similarly priced devices. It doesn't feel flimsy or noisy. In terms of quality and price, this is the best option available.

I find this mouse extremely comfortable to use, especially because I prefer using my fingers to move the track ball.

The ProtoArc Trackball has pleasantly surprised me with its smooth, refined, attractive, and comfortable design. I particularly like the bright orange scroll wheel and the RGB lighting, and the switches feel high-quality. However, the placement of the connection selection switch and the illumination switch could be more convenient if they were on top instead of underneath the device. Adding padding to the palm rest would also be a nice improvement. Overall, it's a very good trackball and is priced reasonably.

The mouse operates smoothly and maintains a strong connection, even though the receiver is placed under the table. It's a bit slow, requiring an increase in cursor speed, but that's a minor issue. It's quite large, making it perfect for slightly larger to large hands.

The mouse meets all my expectations. The price to performance ratio is satisfactory.

I've been searching for years for a trackball mouse that could replace my old Microsoft trackball mouse, and this one finally does the job.

This mouse allows me to work faster thanks to its ball design. It feels comfortable in my hand and is gentle on my wrist. It's particularly effective for editing tables. I would definitely recommend it for its great value for money.

This mouse is exactly what I was looking for. It's extremely easy to use, and I am already thinking about buying another one.

The product is exactly as described and performs accordingly.

The mouse serves its intended purpose well and meets my needs.

In my opinion, this is the best mouse on the market. It closely replicates the design of the discontinued Logitech roller ball mouse. As someone who does a lot of drawing and editing, I find it highly suitable, although it's more comfortable for right-handed use. It offers great value for its price.

This mouse has been a great find for me, especially after shoulder surgery. I can't move my arm without pain using a regular mouse, but the tracking ball on this one makes it pain-free and highly functional.

The product meets my expectations overall. However, I feel the design could have been enhanced to give a more premium feel.

The product is exactly as described and has left me very satisfied with its performance and quality.

Following the instructions made the installation of this trackball a breeze. It operates with exceptional smoothness and the ergonomic design fits comfortably in my hand. The added convenience of the side scroll wheel enhances its usability. In terms of cost-effectiveness, this trackball certainly delivers great value.

The comfort and ease of use of this trackball are noteworthy. Its ability to connect through Bluetooth or with the provided special receiver adds to its appeal. The build quality feels solid and of high standard.

The PROTOARC ergonomic trackball mouse stands out with its fashionable and robust build. It fits comfortably in the hand, is straightforward to set up, and operates seamlessly. The long battery life is a notable feature, and its compatibility with both iOS and Windows PCs adds to its versatility. It's an economical choice that serves as an excellent gift and a great enhancement to laptop and desktop computer accessories.

I am completely enamored with this mouse!

This is exactly what I was searching for, a design that doesn't rely on thumb navigation.

This trackball is impressive, initially appearing somewhat large but quickly becoming comfortable, which enhances its precision. The battery performance is commendable. It's not just battery-operated but also supports charging. The lighting feature can be turned off, and it automatically deactivates in sleep mode. Overall, a superior trackball.

This is the best seller offering the best product. I purchased the trackball EM03, arguably the finest trackball available. Extremely thankful! P.S. I've ordered another one for use at every computer I work with.

This is an excellent trackball, truly worth the investment. My gratitude goes to the seller for the speedy and trouble-free delivery.

It requires a bit of a learning curve but I absolutely adore this product. It's a great budget-friendly ergonomic trackball for home use.

The trackball is highly comfortable and functional.

Sized conveniently between the Elekcom and Logitech models, it offers just the right fit. For those new to trackballs, there's a learning curve, but for experienced users, it provides adequate wrist protection. While it may not have a high-end appearance, it offers great value for its price. Additionally, changing the built-in battery is hassle-free.

This device is intriguing. Initially, it feels unfamiliar, but within 15 minutes, it becomes second nature. The build quality is excellent, with a pleasing touch to the coating. The trackball connects effortlessly to Windows 11, and I find it particularly useful in CAD programs. The battery reliably lasts for about two days, or more precisely, 20 hours. Therefore, I recommend it to those looking to explore new technology. It even performs well in gaming scenarios.

The ball was smaller and less familiar than I anticipated, requiring some time to master. However, I am determined to make good use of it.

The product is of good quality and was delivered pleasantly.

The build quality is commendable, but it's quite unique. The placement of the left button under the thumb instead of the index finger is unconventional, and I'm uncertain if I'll adapt to it. It's an important aspect to consider before purchasing. Additionally, the absence of a soft-touch coating means it can show greasy marks from the hands.

As an enthusiastic gamer, I was initially doubtful about using an ergonomic mouse. But the ProtoArc Vertical Mouse has surpassed my expectations. It's remarkably responsive and comfortable, even after extended use. I would definitely recommend it to both gamers and non-gamers.

The trackball has an interesting design and is priced reasonably for a fully-functional model. However, it requires some getting used to. I purchased it initially for trial purposes, as I already own a trackball mouse from the same manufacturer which I constantly use both at home and work. I've become so accustomed to it that regular mice feel alien to me now. The quality of this trackball is top-notch, with no creaking and rapid response times. The only drawback is the soft-touch coating, which tends to get dirty and might wear out over time. The coating is different on smaller trackballs. Also, the larger trackball's ball is less secure; it falls out if the device is inverted, unlike the smaller one where it stays put even when shaken. The other features are also commendable.

Having used the ProtoArc trackball mouse for a few weeks, I am thoroughly impressed with the battery's longevity between charges. I can go several days without the need to recharge, a significant improvement over my previous mouse.

Fortunately, having purchased numerous trackballs over time, I had a spare ball that fitted perfectly and rolled smoothly.

Working at a desk all day necessitates a comfortable mouse. The ProtoArc has brought a remarkable change. It's comfortable, responsive, and doesn't tire my hand like my previous mouse. I am extremely pleased with this purchase.

The product arrived in good condition.

This finger trackball mouse is pretty awesome; the quality exceeded my expectations.

Working in an office and using a computer all day, I found a significant breakthrough with the Protoarc vertical mouse. It's user-friendly and has notably alleviated my wrist pain. I strongly recommend it for anyone who spends extensive time at the computer.

The mouse feels pleasant in hand and is conveniently usable with the left hand as well. It offers great flexibility for different hand preferences.

The Protoarc wireless trackball mouse is fantastic! Its rollerball operates smoothly, and the thumb control is very comfortable. The ability to switch between devices seamlessly is a big plus. Its a stylish addition to my desk setup. I highly recommend it!

Recently, due to wrist pain from my job, I sought a new ergonomic mouse, and the ProtoArc has been perfect! It's extremely comfortable, and I've noticed a significant decrease in my wrist pain since I began using it. I highly recommend it!

I am very grateful for this product.

As my first trackball, I lack a basis for comparison with other devices. However, the quality of this one is superb. It arrived well packaged, and the delivery was swift. The ball rolls smoothly, and the left/right buttons have a silent click. The forward/back buttons provide a tactile clicky feedback. Overall, I am delighted with the trackball and commend Proto Arc for producing such a high-quality product at a competitive price.

This device is intriguing. Initially, it feels unusual, but it quickly becomes familiar within just 15 minutes. The build quality is excellent, with a coating that feels pleasant to touch. The ball rotates effortlessly, and it connects seamlessly to Windows systems. As someone who works in CAD programs, I find the battery life, lasting about two days or 20 hours, to be very reliable. Therefore, I recommend it for those looking to try something new. It even performs well in offline gaming.

This is an excellent product that I highly recommend. I do wish they would offer a wired version, as the precision of the pointer would likely be higher, and there would be no concerns about battery life.

Spending all day at the computer, this mouse has been a game-changer. Its engineering design has effectively eased my wrist pain and it's extremely user-friendly. I definitely recommend it to anyone who spends a lot of time working on a computer.

Everything is good. Thank you.

The item arrived well-sealed! This wireless and stationary mouse accommodates three devices: a notebook, Palm, and Mobile, and can switch between them with just a touch. I'm still learning to use its various button functions but am very satisfied so far. The angle positioning and control via the movement of the sphere are the standout features of this item.

Working in flat design, a mouse that offers precise movement and control is essential. The Protoarc trackball mouse achieved this from the start. The trackball facilitates easy control over curves and paths. Its design, compatible with human body engineering, ensures comfort even during long design processes.

This is a good product; I recommend it.
