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. Review: The Real Value Buy over the Logi MX ERGO+ - Great value for the price, it definitely competes with the Logi(tec) MX EGRO Plus, it has all the same or simmilar features (from what I have used it for) - same buttons, sensitivity button, scroll buttons, wrist angle adjustment plate, usb C connector/charging port, thumb movement is good and feels similar, and it has one improvement: you can connect it to 3 different devices (vs 2 w the logi). Trackball Tangent: This is a great trackball mouse for those who know they like them, and for those looking to try one, this is a good buy, if you have never used one, you should expect to spend a couple hours getting used to it, and probably a month to get fully comfortable. Benefit: If you use a laptop or tv for your computer needs, a track ball is great because you dont need a sturdy table, you can hold it on the couch or even your leg, thus allowing for mouse, or keyboard & mouse in far more situations/locations. Note: I paid $38.69, and it looks to be even cheaper ($29) at the moment, and I thought I got a great deal. Note 2: If they are close in price when you are shopping, get the purple or yellow/gold ball version, those have proper amounts of flair (I messed up and got the grey version :( ) ## 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 | | Batteries | 1 Lithium Ion batteries required. | | Best Sellers Rank | #100 in Computer Mice | | Customer Reviews | 4.3 4.3 out of 5 stars (2,749) | | Date First Available | May 13, 2024 | | Item Weight | 11.6 ounces | | Item model number | EM01 NL | | Manufacturer | ProtoArc | | Product Dimensions | 3.54 x 2.76 x 0.04 inches | ## 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 Wireless Trackball Mouse, EM01 NL Ergonomic Bluetooth Rollerball Thumb Rechargeable Computer Laptop Mouse, Adjustable Angle & 3 Device Connection for PC, Mac, Windows-Red Ball - Image 1](https://m.media-amazon.com/images/I/61aW3yXUtZL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.

I'm 6'5" with large palms and long fingers so I needed one that could support (most of) my hand with minimal wrist and knuckle fatigue or finger crowding. I've rated them by personal preference below: 1. Nulea M501 ($33.99). Clever clone of the Logitech M570 even down to the defined separate grooves/shelves for ring finger and pinky, which helped separate my fingers for less crowding. Professional packaging and instructions. Added bonus of USB dongle + 2 Bluetooth channels and charging via USB-C port (vs. AA battery). Nulea's website also offers a fast and convenient customer service messenger chat, which I used when I initially had a problem connecting via Bluetooth (FIXED). Can't recommend enough. I also picked up the black/red Anleo Hard Travel Case ($9.59) to match so I can throw it in my backpack and not worry about it. This is the one I ended up keeping. 2. ProtoArc EM01 NL ($47.99) a mashup in looks and features of a Logitech M575S and MX ERGO ($99.99) but at a less insane price. Classy black professional box packaging. The mouse really feels like a quality product and has great features and design. I really liked the 2 angles you can adjust the mouse to suit your wrist. Perhaps the thing it was missing for me was that my ring and pinky fingers were too crowded and shared the same space. I also decided I wasn't a fan of the mushier quiet buttons and preferred a tactile/audible click. 3. MicroPack Trackball Vertical Mouse ($29.99). You get what you pay for here. Minimal features and feels noticeably cheaper; same with the basic packaging. The more extreme "natural handshake" vertical angle was a little too much for me and at the time I preferred the ProtoArc EM01 NL more, although to be honest I felt MicroPack's trackball actually ran slightly smoother on the screen. 4. Logitech Ergo M575S ($49.99). Purchased from local office store before returning it because it felt smaller and ironically less ERGOnomically comfortable than my original M570, and for $49.99 it still ran off a AA battery. I also decided I wasn't a fan of the mushier quiet buttons and preferred a tactile/audible click. ## 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.pl/products/643449956-protoarc-wireless-trackball-mouse-em01-nl-ergonomic-bluetooth-rollerball-thumb](https://www.desertcart.pl/products/643449956-protoarc-wireless-trackball-mouse-em01-nl-ergonomic-bluetooth-rollerball-thumb) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-08*
