Review: A really nice comfortable mouse replacement. - I've been using this daily now for almost a year and I find it much more comfortable to use and easier on the wrist than a regular mouse. I bought it to try because I was feeling strain from clicking and holding the middle mouse button whilst also moving the mouse which you have to do a fair bit in Blender and other 3D software. This type of mouse solved my problem as I'm no longer fighting my own grip. It's also a space saver as you no longer need to move the mouse around the desk. This is my first trackball mouse but I quickly adapted and within a couple of days I was just as accurate at moving the ball as I was pointing with a regular mouse. I don't have much to compare to but the build quality feels solid. I've not had any connectivity issues or issues with glide or smoothness, and it works well switching between different devices. The battery lasts a few months between charges and you can use it while charging too. The buttons are all nice to click in both orientations (flat or tilted) and the sensitivity is just set once and forget. You do have to pop the ball out to remove dust occasionally but it appears that's just expected maintenance with this kind of mouse. There's a handy hole you can push something through to help with popping it out. I'm really happy with this purchase and it has become part of my every day setup. I'm not sure how it weighs up against more expensive models but I'm happy enough and not looking to upgrade any time soon. Review: Best for small hands, if that is you, then it will be good for you. - I would say a good trackball device. This was a quick purchase because my logi mx buttons are now prone to bounce with tragic in some cases accidental double clicks. Would say this is lighter and the tilt angle seems to be less. I would recommed as a good product at the price. Things I miss from the far more expensive Logitech model. The DPI settings steep up and down with two buttons on this trackball but the logi has a instant button to drop the DPI right down when you need to make a very precise movement. It would be good to be able to change the response of the wheel as it is great for Windows but far too slow for Macs which are tailored for the touchpad scrolling on the top surface of the mouse. Also what makes this less than perfect for me is that the tackball is shaped for smaller hands. If this is you then it could be the perfect device, for me though the wheel is about 1cm too far back for me to use, I have to change my grip to do so, not good for all day use. ## Features - Ergonomic Thumb Mouse: Track precisely with great cursor control on any surface and easy thumb-operated trackball. You no longer need to move your arm for the movement of the cursor. It will effectively reduce fatigue and strain for your wrist and arm. - Adujustable Angle Design: Unique adjustable hinge allows you to customize the trackball angle from 0 to 20 degrees according to your needs for a more natural, comfortable hand position and less muscle strain. - Rechargerable & Adjustable DPI: The Bluetooth Trackball Mouse built-in 900mAh lithium battery. No need to change batteries. It can last 1 month per one full recharge. 5 DPI levels (200/400/800/1200/1600 DPI) allows you to change the cursor sensitivity easily and track more smoothly over a variety of surfaces - Bluetooth & 2.4G Wireless Connection：PLUG and PLAY. This trackball mouse has triple connection modes. You can control three devices at the same time, switch freely between Android, tablet and Mac with just one button. Compatible with Windows, Android, Mac OS PC Laptop Desktop etc - Optimal for Tight Workspaces: Because the trackball doesn't move, it’s excellent for tight workspaces and busy desks and fits in seamlessly alongside your computer and keyboard or laptop. Note: The backward and forward button is not fully compatible with MAC - 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 - Are you new to trackball mouse? 1.

The ball has a nice smooth glide action coupled with accurate pointer movements. It is very comfortable to use and the tilt action makes it even more comfortable. I thought it was a bit of a gimmick when I read it in the advert, but having used it for a month or three now, the tilted angle is the most comfortable way to use the mouse. The connectivity is good and you can still use the mouse whilst charging. So there shouldn't be any down time. ## Frequently Bought Together - ProtoArc Wireless Trackball Mouse, EM01 NL Ergonomic Bluetooth Rollerball Thumb Mouse Rechargeable Computer Laptop Mouse, Adjustable Angle & 3 Device Connection for PC, Mac, Windows-Red Ball - Hermitshell Hard Travel Case for RGB Wireless Trackball Mouse ProtoArc EM01 2.4G Bluetooth Ergonomic Rechargeable Rollerball Mice --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/674258602-em01-nl-wireless-bluetooth-trackball-mouse-adjustable-angle](https://www.desertcart.pt/products/674258602-em01-nl-wireless-bluetooth-trackball-mouse-adjustable-angle) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-26*
