Review: Excellent vertical design is super comfortable - Super comfortable, vertical design is superb for long hours and the configurable DPI setting enables flexibility for different tasks. Forward/back buttons make browsing research quick. Battery life is excellent, I work using this mouse 5 days a week 8-10 hours and recharge this once every 5 weeks maybe? Overall an excellent and worthwhile investment.
Review: A definite upgrade to websearching and PDF reviews - This is an initial review after a full day's use of the mouse, but I'm pleased with the mouse so far. I didn't think I'd find an upgrade to a rollerball mouse, but even the small things, like the buttons on this mouse, and the placement, already make my functional use so much better. I really liked my previous mouse, actually my last 2, but in each new upgrade, the angle of the mouse and reach of the ball felt a little more comfortable than the last. This is an exceptional upgrade in how my hand feels holding the mouse, moving my thumb, and using the buttons. It took a minute to get used to the new position, then realizing the functions of the buttons, quick ease to change the cursor speed, not that I need that much, but useful. The forward and back buttons, especially useful in webpage surfing, is great, and easy to get to without really thinking about the button placement. The real think is the comfort of mouse setting. As I deal with maps, imagery, and coding, I don't like taking my eyes off the screen, and should be able to find my keyboard and mouse easy just by last placement, not by eyeing where they are. This should be a comfort level. As I'm already used to a rollerball mouse, this placement is already good, but now putting my hand down on the mouse, the way this mouse sits just feels more comfortable, and the wear and stress on my thumb is lower. This, however, is on personal use of the mouse. I've used flat rollerballs that use index finder, index and middle, and thumb rollers. I can function with any with ease, but extended use tires the fingers, especially from mouse to keyboard, moving screen items and typing. So far, I like this mouse. The design of the mouse seems to take up some more space than my previous model, I think mainly how the bottom of this spreads out for stability and comfort on your palm. Using this in conjunction with a small gel wrist rest, feels really comfortable in prolonged use. I have been really friendly with Logitech products, especially like their rollerball mice, and it comes down to the tracking. The last mouse was an off brand. While the mouse was nice, it held up well, the tracking and smooth movement wasn't there. For general document management and webpage surfing, it was fine. For precision work, it was not. The tracking on this, so far, is perfect, smooth, but this is so far just the first day use. Let's see over time. My previous off brand, tracking was never smooth, and sometimes quite frustrating. I'm not seeing with this, so far. I like this mouse, it's held up well to the first day use. It charged up well, came with minimal charge to at least get started, then we useable while charging. I'm using the USB, but this has Bluetooth function, if you go this direction. I'm happy with the USB. I'll write more later on the other connectivities. Each mouse is dependant on the user, use, function, and wear and tear on the hand placement, finger use, and overall ergonomic comfort. This works very well for me, thumb use, and placement of the hand. If you get a lot of thumb wear, this has some ease to it, and when not using the thumb, it has a natural resting place on the mouse. And the button functions, in turn, make this mouse quite functionable.

## Features

- Ergonomic Design for Natural Grip: The vertical design of a 62 degree tilt and natural handshake can perfectly fit the palm of your hand, keeping your arms and wrists in a relaxed state, so that you won't feel tired after a day of work
- Bluetooth & 2.4G Wireless Connection：PLUG and PLAY. This trackball mouse has triple connection modes(2.4G+BT 5.1+BT 3.0). You can control three devices at the same time, switch freely between Android, tablet and Mac with just one button. Note: all the buttons are non-programmable and the backward forward buttons are not compatible with Mac OS system
- Thumb Trackball Mouse: Equipped with a smooth trackball, move your cursor with your thumb movement instead of moving your wrist and arm. It will effectively reduce fatigue and strain for your wrist and arm. Not only work on flat surfaces, but also on your leg, sofa and other surfaces as well, especially in a narrow space, such as the messy desktop
- Rechargeable & Quiet Clicking: The vertical trackball mouse equipped with a build-in rechargeable battery, could be recharged easily with the included USB-C cable. Please remember to turn it off if you do not use it for a long time. Smooth frosted surface and quiet clicks can bring a better user experience and free your worry about bothering others and keep you stay focused while working
- Wide Compatibility & Adjustable DPI: This vertical rollerball mouse is suitable for laptop/PC/notebook/tablet/Macbook/ipad/iPhone. It is compatible with Windows, Android, Mac OS etc. 5 DPI levels (200/400/800/1200/1600 DPI) allows you to change the cursor sensitivity easily for more precise tracking
- After using the trackball for a period of time, please clean the trackball and the three white rollers inside the hole to ensure that the trackball is always smooth. Note: When the computer is just started or a large application is running, it may also cause the trackball to not run smoothly
- Warm Tips: Since it takes a learning curve to get used to the control method when using our trackball mouse for the first time, it may cause inconvenience to your mouse grip, you can experiment with different hand positions to find what is most comfortable for you. We recommend that you take 1-2 weeks to get used to it, as many users find that it will help reduce the pressure and pain on your wrist caused by long-term use of the mouse and improve comfort
- Please note that this product is designed as a pure trackball mouse, which is fundamentally different in its interaction method from traditional optical mice. It cannot control the cursor by moving the device itself like a standard optical mouse. Please read carefully before placing your order.

### ⭐⭐⭐⭐ Good trackball with some slight issues for my thumb.
*by J***R on June 24, 2025*

I have used a trackball for many years and was looking to get one that would be a replacement for my old Logitech m575. I wanted to try an ergonomic design and this ProtoArc EM05 looked like it would fit the bill. It is very nicely made and I really like the tilt angle for the hand. I have only 2 concerns at the moment. 1. Ball placement and size - It seems to be a little too far back and up for my thumb to be comfortable on the ball. The ball is small so making precise movements and selections are a little difficult. 2. Slick surface - The texture and feel of the coating on the surface are very slippery to me. I find it hard to get a grip when I need to move it around on the desk, or pick it up to get to the buttons and switches on the bottom. Overall, it connected well with a Bluetooth connection and for the price, I think it is a good value trackball. I am not sure I will be keeping it though and still looking for and alternative.
