The ProtoArc EM01 NL is the right entry point into thumb trackballs β€” 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 β€” 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 β€” 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 β€” 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: Best Trackball I have ever owned! - I love this trackball. I originally had a Logitech, which stopped making these kinds of trackballs. So I bought this to replace it, and I love it more than the Logitech, and it was about a third of the price. It has more features and has not failed me yet. It's comfortable; the ergonomics of it are great, especially the tilt. The scroll wheel is still going great and has multiple functions. The size is perfect. It is easy to use with plug-and-play. The material is great, especially the metal magnetic plate it tilts on. I also LOVE the purple trackball! I'd like it to work via Bluetooth or while plugged in. The Bluetooth on my laptop stopped working, so I would have liked to use this just with the wire. But other than that, this is the best trackball I have had. I would get it again, but it is still running strong! ## 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.

I would get it again, but it is still running strong! ### ⭐⭐⭐⭐⭐ Very Very Premium, Very Very Good *by A***R on December 30, 2025* 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. ## 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-Silver Ball - Hermitshell Hard Travel Case for ProtoArc Wireless Trackball EM01 NL Ergonomic Bluetooth Rollerball Thumb Mouse Rechargeable Computer Laptop Mouse --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/648164490-protoarc-em01-nl-wireless-trackball-mouse-thumb-control-silver](https://www.desertcart.sk/products/648164490-protoarc-em01-nl-wireless-trackball-mouse-thumb-control-silver) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-07*
