## Description

desertcart.com: ProtoArc EM01 NL Wireless Trackball Mouse, Thumb Control, Purple : Electronics

Review: Ergonomic game changer — three device connectivity makes it perfect for work from home - Been using traditional mice for years and the wrist fatigue that comes with extended desk sessions finally pushed me to make the trackball switch. The ProtoArc EM01 NL is the right entry point into thumb trackballs — ergonomic design, wireless Bluetooth, rechargeable, and multi-device connectivity that makes it the ideal work from home peripheral. The three device connectivity is the feature that separates this from a standard wireless mouse. Two Bluetooth device pairings plus a USB dongle receiver means you can have a work laptop, personal machine, and a third device all paired simultaneously and switch between them with a button press. For a work from home setup where you're bouncing between a company laptop and a personal machine throughout the day this is a complete workflow changer — one mouse, no re-pairing, instant switching. The thumb trackball placement is the ergonomic win that makes this style of mouse worth switching to. Wrist stays stationary while the thumb does the tracking work — after a few days of adjustment the precision is there and the wrist fatigue from constant mouse movement is completely gone. For anyone doing long desk sessions whether work or home lab, the difference is real and noticeable. Bluetooth connectivity is solid and stable across all paired devices — no lag, no dropout, no cursor jumping. Pairs quickly on initial setup and reconnects immediately when switching between devices without the delay that plagues some wireless peripherals. Rechargeable battery life is strong enough that charging is an occasional task rather than a constant concern. USB-C charging means one less proprietary cable to manage. For anyone working from home across multiple machines, the three device pairing plus trackball ergonomics makes this an easy recommendation. Highly recommended.
Review: Very Very Premium, Very Very Good - I have to say almost 6 days coming up on a year after buying this mouse, its perfect. Its funny cause when i bought this, i didn't really sift its specs thoroughly, didn't know physically moving the mouse didn't move the cursor, I just bought it because it looked good & it shipped fast. First off, the build quality is amazing, it feels and weighs very premium. love the fact that I can just recharge it with usb c. when I first got it, it took about 4 hours to get used to it because before it, the mouse i had was regular, so hand positioning was a bit awkward at first but after those hours i loved it. Never going back. Its very smooth and the scrolling is so good and easy to adjust. love that. One thing that's weird about it (or weird about me) is that u can use this while sitting in your chair (place it on the arms rest), standing up, on your lap, or laying down in your bed for tv (i use a projector). Its comfortable in every way. Although i said it took 4 hours to get used to, gaming took a bit longer, but over time it becomes way easier and honestly in my opinion, more convenient than a regular mouse. Reason why I say this is because for some people like me, our table may not have a lot of room to move the mouse, but with the rollerball, the ease of it is crazy. The battery lasts so long, I just charge it for the sake of seeing it charged, never for the sake of "its almost dead, or it died, lemme go charge it", if that makes sense. And the smooth connectivity is awesome, switches between devices like its nothing, the distance i can use it at is very good and I love the number-lights thing. Once you buy this mouse, you wont believe the quality you got for the price (compared to others). If the rollerball gets a bit slow or choppy, all I have to do is use my thumb and forcefully roll the ball until it feels smooth again, which i rarely have to do but its a quick fix, no extra steps. Overall, it feels awesome, performs awesome, and its aesthetic is awesome.

## Features

- Adjustable Trackball Comfort: The 0-20° hinge lets you set the trackball angle to match your hand position, supporting a more natural grip through long work sessions
- Thumb-Control Precision: Navigate documents and web pages by moving the thumb trackball instead of your whole arm, making it easier to work on crowded desks, couches, or beds
- 3-Device Wireless Control: Bluetooth and 2.4G wireless modes let you connect up to three devices and switch between PC, laptop, and tablet with one button
- Rechargeable 5-DPI Tracking: The built-in rechargeable battery avoids disposable battery swaps, while 200/400/800/1200/1600 DPI levels adjust cursor speed for different tasks
- Quiet Shared-Space Clicks: Quiet left and right clicks and a frosted surface support focused work in offices or home spaces; scroll wheel and side buttons are not silent
- Easy Trackball Maintenance: Clean the trackball and three white rollers after extended use to help keep movement smooth, especially after startup or heavy app loading
- Health Tip: Like any ergonomic tool, trackball mice require a short learning curve. Unlike traditional mice, they keep your wrist stable – a more natural motion that reduces pressure and fatigue. Most users adapt within 1–2 weeks. Experiment with hand positions to find your comfort. Our goal: healthier, pain‑free use for years

### ⭐⭐⭐⭐⭐ Effortless and Quality Mouse - A Definite Buy (Recommend Buying)
*by J***E on April 19, 2026*

A definite buy if you are looking for a trackball mouse. Build quality is pretty good and it feels effortless to use the mouse. Trackball movements/motions are very very smooth. Very smooth scroll wheel. Left/Right click buttons require perfect amount of very light pressure to work, therefore the fingers wouldn't get tired after continuous use and same for the forward/back button. Click sounds while using the mouse are very subtle and just loud enough for you to hear the action. The DPI levels (the cursor speed) buttons have 5 levels that are perfectly spaced for varied needs. Size of the mouse and curves/arcs on the mouse are well designed and thought of for ergonomics and comfort and not to forget the 20 degree angle plate at the bottom of the mouse allows you to change the angle of the mouse, is a big plus. It can connect to 3 devices and I had no issues connecting it via Bluetooth. Only drawback is there is no storage for USB receiver/dongle on the mouse and it has to be stored separately, I would recommend ProtoArc to improve on this aspect. Another suggestion would be to provide the ability to customize the back/forward buttons to actions that user prefers. I also own a Logitech trackball mouse but after using ProtoArc's effortless mouse, I am NOT going back to Logitech.
