Wireless Bluetooth Ergonomic Trackball Mouse with RGB Backlight

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.
