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.
Review: Easy to use - works great - Wasn’t sure I would like the vertical trackball but I’ve grown so used to it that it’s now my preference. The battery life is great and the buttons are holding up well. Much easier than a mouse for RTS games in my opinion. The cursor can jump quickly by default but you can adjust it in the settings. I like this one and will probably get it again when it breaks down. Seems pretty sturdy though so I’m expecting at least a 6-7 year lifespan here. I’m 6’2” with average hands for my size. The feel is nice and the wheel works great. It’s a little bulky so many not your “travel” trackball but a perfect one for the default desk work.

## 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

### ⭐⭐⭐⭐ A Great Alternative to a Std Vertical Mouse, as well as to a Std Mouse & to a Std Trackball Mouse
*by L***J on December 10, 2024*

I just received this alternative to a Std Mouse, (to a Std Trackball Mouse, and to a Std Vertical Mouse), and I must say it is all it claims to be in terms of use and functionality. The buttons work very well in their designed locations and the trackball ensures I minimize my hand/arm movements. I am enjoying the user experience. I had long ago moved from using a Std Mouse to using the Trackball alternatives, (of which I highly recommend the Kensington, Nulea, & Logi-tech options if someone is not ready to move to a Vertical Mouse). So while my current favorite option for a Std Mouse is the Logitech Ergo Trackball Mouse, when it was recently liberated (ie lifted/stolen) from my temporary workstation location, I decided it was high time to try the Vertical options available. I looked and tried several Vertical Mouse options, and although fairly comfortable with a few, I missed the use and functionality of having a Trackball Mouse. So when I discovered that Kensington & Logi-tech and a few other brands had some Trackball Vertical Mouse options I was thrilled. After reviewing the, (limited), options available I ended up selecting the ProtoArc Vertical Wireless Trackball Mouse, EM05 NL Bluetooth Ergonomic Rollerball Mouse for the following reasons: 1> A "true" vertical mouse setup with a 62' Tilt 2> A rechargeable mouse. Charging via a Type C USB cable option, with an included charging cable. 3> A 2.4 Hz Dongle along with Blue-tooth wireless connectivity options 4> Compatible with both Apple / Mac, Windows, PC Android, (this means in a pinch my significant other can use it as well for her Mac). As noted above I just received this mouse and have been putting it through its paces and so far, I think it's excellent. However, I am giving it 4 of 5 Stars, (as the system is not allowing me to give a 4.5 out of 5), for the following reasons: A> The trackball could be a little bigger even though it is thumb-specific, I have found the tracking of the larger trackballs for finger control tends to be a little easier to use, and therefore I would like the thumb trackball to be a little larger for that control. B> The Dongle could be set up for easier visibility. I find that keeping the Top and connecting edge Black requires a bright lighted area to ensure it is connected correctly and smoothly. So a brightly colored top and a white, (or other bright color connecting edge to the USB portion), would allow for faster and easier connection setup. C> Non-Programmability of Buttons prevents customization D> Lack of covering for the charging port and Dongle insert areas would be a plus from my perspective With that said, besides what I noted above, I also have the following recommendation: E> The creation of a Travel Size version of this or other Vertical Mouse. (As noted above I was using the Logitech Ergo Trackball Mouse and although it's big, I had a case for it so it allowed me to take it for some limited travel, so having the option to purchase a case would be a very good option. However, when doing serious traveling I defaulted to using a "miniature version" of the Std Mouse as space becomes a major restriction. So even with the feedback given above, I do want to stress that overall I am very happy with this ProtoArc Vertical Wireless Trackball Mouse, EM05 NL Bluetooth Ergonomic Rollerball Mouse, and I would highly recommend it to anyone, especially to those interested in transitioning to a vertical mouse and to anyone who would also appreciate having access to trackball functionality as well.
