Customizable angle design reduces wrist/arm strain for comfortable, precise cursor control. Review: I really like this mouse, said Sylvester. - This is a brilliant mouse. 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. Review: Great Quality, and value - would recommend. - I have to say, I love my Logitech MX Ergo. I have one at home and in the office. But when I saw this, and it was on Prime Day deal. I had to try it. ProtoArc have taken the MX Ergo and made some subtle but very good improvements. The Logitech is paired with my favourite K860 keyboard, but there's a slight design flaw. The keyboard can switch to 3 devices, the mouse only 2. The ProtoArc mouse not only solves this, it provides a nice way of doing so. Use option 1 with the 2.4MHz Wi-Fi dongle it comes with, or use option 2 or 3 with Bluetooth. This is awesome. Bluetooth switches so easily that it's pretty much an infinite selection, but with two favourites. Then there's a very simple but overlook feature on the Logitech. You have to take it off the magnetic plate to pop out the ball to clean it. ProtoArc made a simple change, put a hole in the plate aligned with the ball removal hole - genius. There is ONE thing I don't like. The roller has teeth, feels a little to rough on my baby smooth fingertips. But other than that, I can't fault it. For the £28 it cost me, a big saving over the £89 Logitech it's a great bit of kit. ## Features - Ergonomic Thumb Mouse: Track precisely with great cursor control on any surface and easy thumb-operated trackball. The trackball cannot be used in the same way as a regular mouse. 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 during long working hours - Rechargerable & Adjustable DPI: The Bluetooth Trackball Mouse built-in 900mAh lithium battery. No need to change batteries; battery life lasts up to 1 month per 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. While excellent for daily tasks, it is not optimized for competitive gaming. - Bluetooth & 2.4G Wireless Connection：PLUG and PLAY. This trackball mouse has triple connection modes and comes with a USB receiver dongle. 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; however, forward/backward buttons are not compatible with Mac OS. - 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. It features a standard scroll wheel for easy navigation, though all buttons are not programmable. - MAINTENANCE & CLEANING: After using the trackball for a period of time, please clean the trackball and the three white rollers inside the hole to ensure smooth tracking performance. Note: When the computer is just started or a heavy application is running, it may temporarily cause the cursor to lag. - GETTING USED TO YOUR TRACKBALL: Are you new to a trackball mouse? 1. Be patient and give yourself an adaptation period to get used to the unique thumb-operated style. 2. Experiment with different hinge angles to find what is most comfortable for your wrist. 3.

But when I saw this, and it was on Prime Day deal. I had to try it. ProtoArc have taken the MX Ergo and made some subtle but very good improvements.

The trackball itself isn't bad and provides decent control, but it does require frequent cleaning to maintain a smooth experience. I got it as an alternative to the Logitech MX ERGO, but unfortunately, it doesn't quite match up in terms of precision and overall smoothness. While it’s a good option for basic use, if you’re looking for something that can rival the MX ERGO’s performance, this may not be the best fit. Still, for its price, it’s a solid choice for casual use. ## Frequently Bought Together - ProtoArc Wireless Trackball Mouse, EM01 NL Ergonomic Bluetooth Rollerball Thumb Rechargeable Computer Laptop Mouse, Adjustable Angle & 3 Device Connection for PC, Mac, Windows-Gray Ball - Hermitshell Hard Travel Case for ProtoArc Wireless Trackball EM01 NL Ergonomic Bluetooth Rollerball Thumb Mouse Rechargeable Computer Laptop Mouse --- ## 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.id/products/640170345-protoarc-em01-nl-wireless-bluetooth-trackball-mouse-2-4g-ergonomic](https://www.desertcart.id/products/640170345-protoarc-em01-nl-wireless-bluetooth-trackball-mouse-2-4g-ergonomic) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-08*
