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: 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 - Ergonomic Design for More Comfort: Unique adjustable hinge allows you to customize the trackball angle from 0 to 20 degrees according to your needs, ensuring a more natural, comfortable hand position for all-day comfort - Precise Thumb Mouse: ProtoArc trackball mouse provides accurate and smooth tracking, allowing for easy navigation through documents and web pages. You no longer need to move your arm for the movement of the cursor. Your thumb will control the cursor instead via the trackball. It will effectively reduce fatigue and strain on your wrist and arm. More productive in the narrow space, such as the messy desktop, couch, bed etc - Bluetooth & 2.4 G Wireless Connection: PLUG and PLAY. This trackball mouse has triple connection modes. You can control three devices at the same time, switch freely between PC, laptop and iPad with just one button to improve your efficiency. Compatible with Windows, Android, Mac OS PC Laptop Desktop etc - Rechargeable & Adjustable DPI: The bluetooth Trackball Mouse built-in rechargeable lithium battery. No need to change batteries. Please remember to turn it off if you do not use it for a long time. 5 DPI levels (200/400/800/1200/1600) allows you to change the cursor sensitivity easily and track more smoothly - Quiet Clicking: 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. Note: The middle scroll wheel is not silent. All the buttons are non-programmable and the back forward buttons are not compatible with Mac OS system - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CWTVY6WQ | | Additional Features | Adjustable Angle, Ergonomic Design, Quiet, Rechargeable, Wireless | | Antenna Location | Office | | Best Sellers Rank | #134 in Computer Mice | | Brand | ProtoArc | | Button Quantity | 8 | | Color | Red Ball | | Compatible Devices | Desktop Computer, Laptop, Personal Computer, Smartphone, Tablet | | Connectivity Technology | 2.4G Wireless | | Customer Reviews | 4.2 out of 5 stars 3,352 Reviews | | Enclosure Material | Plastic | | Finish | Matte | | Hand Orientation | Right | | Hardware Platform | Linux | | Item Weight | 0.33 kg | | Manufacturer | ProtoArc | | Mfr Part Number | Protoarc B0CWTVY6WQ | | Model Number | EM01 NL | | Mouse Maximum Sensitivity | 1600 dots_per_inch | | Movement Detection | Trackball | | Movement Detection Technology | Trackball | | Number of Batteries | 1 Lithium Ion batteries required. | | Number of Buttons | 8 | | Operating System | Android, Mac OS, Windows | | Power Source | Battery Powered | | Range | 10.0 meters | | Special Feature | Adjustable Angle, Ergonomic Design, Quiet, Rechargeable, Wireless | | Style Name | Modern | | Unit Count | 1 Count | | Warranty Description | 2 Year Warranty | ## Product Details - **Brand:** ProtoArc - **Color:** Red Ball - **Connectivity Technology:** 2.4G Wireless - **Movement Detection Technology:** Trackball - **Special Feature:** Adjustable Angle, Ergonomic Design, Quiet, Rechargeable, Wireless ## Images ![ProtoArc EM01 NL Wireless Trackball Mouse, Rechargeable Thumb Control, Red - Image 1](https://m.media-amazon.com/images/I/61aW3yXUtZL.jpg) ![ProtoArc EM01 NL Wireless Trackball Mouse, Rechargeable Thumb Control, Red - Image 2](https://m.media-amazon.com/images/I/61Gqut2HlEL.jpg) ![ProtoArc EM01 NL Wireless Trackball Mouse, Rechargeable Thumb Control, Red - Image 3](https://m.media-amazon.com/images/I/71GHpDH4K4L.jpg) ![ProtoArc EM01 NL Wireless Trackball Mouse, Rechargeable Thumb Control, Red - Image 4](https://m.media-amazon.com/images/I/71YI66U0+yL.jpg) ![ProtoArc EM01 NL Wireless Trackball Mouse, Rechargeable Thumb Control, Red - Image 5](https://m.media-amazon.com/images/I/71PsdJoMitL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ergonomic game changer β€” three device connectivity makes it perfect for work from home *by J***E on July 23, 2026* Been using traditional mice for years and the wrist fatigue that comes with extended desk sessions finally pushed me to make the trackball switch.

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. ## 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? - 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.de/products/643449956-protoarc-em01-nl-wireless-trackball-mouse-rechargeable-thumb-control-red](https://www.desertcart.de/products/643449956-protoarc-em01-nl-wireless-trackball-mouse-rechargeable-thumb-control-red) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-08-28*
