Designed for tight workspaces, it’s compatible with Windows, Mac, and Android, making it a versatile productivity tool for professionals. ## Description Ergonomic trackball mouse with 3 adjustable DPI and 3-device Bluetooth. Customizable angle design reduces wrist/arm strain for comfortable, precise cursor control. ## 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. If you need assistance with setup or usage, please contact our customer service. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CWTY6Z99 | | Antenna Location | Business, Home, Office, Personal | | Are Batteries Included? | No | | Are Batteries Required | Yes | | Battery Average Life | 30 days | | Best Sellers Rank | 5,681 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 4 in Trackballs | | Box Contents | A Type C Charging Cable, A USB Receiver, A User Manual, An Ergonomic Trackball Mouse | | Brand | ProtoArc | | Brand Name | ProtoArc | | Button Quantity | 6 | | Colour | Gray Roll | | Compatible Devices | Laptop, Personal Computer | | Connectivity technology | Bluetooth, USB | | Country of Origin | China | | Customer Reviews | 4.3 out of 5 stars 3,421 Reviews | | Enclosure Material | Plastic | | Hand Orientation | Right | | Hardware Platform | Personal Computer | | Item Weight | 0.35 Kilograms | | Manufacturer | ProtoArc | | Manufacturer Part Number | Protoarc B0CWTY6Z99 | | Model Name | EM01 NL | | Model Number | EM01 NL | | Mouse Maximum Sensitivity | 1600 Dots per Inch | | Movement Detection | Optical | | Movement detection technology | Optical | | Network Connectivity Technology | Bluetooth, USB | | Number of Batteries | 1 Lithium Ion batteries required. | | Number of buttons | 6 | | Operating System | Windows, Android, Mac OS | | Power Source | Battery Powered | | Product Features | Ergonomic Design, Portable, Rechargeable, Wireless | | Product Finish Type | Smooth | | Range | 10 | | Special feature | Ergonomic Design, Portable, Rechargeable, Wireless | | Style Name | Modern | | Theme | Video Game | | Unit Count | 1.0 count | ## Product Details - **Brand:** ProtoArc - **Colour:** Gray Roll - **Connectivity technology:** Bluetooth, USB - **Movement detection technology:** Optical - **Special feature:** Wireless, Portable, Rechargeable, Ergonomic Design ## Images ![EM01 NL Wireless Bluetooth Trackball Mouse Adjustable Angle - Image 1](https://m.media-amazon.com/images/I/61fesDeGRKL.jpg) ## Available Options This product comes in different **Color** options. ## 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.vn/products/640170345-em01-nl-wireless-bluetooth-trackball-mouse-adjustable-angle](https://www.desertcart.vn/products/640170345-em01-nl-wireless-bluetooth-trackball-mouse-adjustable-angle) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-08-26*
