## Description

Product Description EM01 NL Trackball Mouse Note When using the trackball for the first time, slight thumb soreness is normal as it's a muscle memory rebuilding process. We suggest spending 1-2 weeks getting used to it. Many users find this reduces wrist pressure and pain from long - term mouse use and increases comfort. Note: All buttons are not programmable. Backward/forward buttons are not compatible with the Mac OS system Clean the Trackball When you use the trackball mouse for a period of time, you need to clean the trackball and inside the hole to ensure that the trackball is always smooth. Adjustable DPI 5 DPI levels (200/400/800/1200/1600 DPI) allows you to change the cursor sensitivity easily for more precise tracking. 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.

Review: I really like this mouse, said Sylvester. - This is a brilliant mouse. The ball has a nice smooth glide action coupled with accurate pointer movements. It is very comfortable to use and the tilt action makes it even more comfortable. I thought it was a bit of a gimmick when I read it in the advert, but having used it for a month or three now, the tilted angle is the most comfortable way to use the mouse. The connectivity is good and you can still use the mouse whilst charging. So there shouldn't be any down time.
Review: Solid Performance, But Falls Short of the MX ERGO - The ProtoArc EM01 NL Wireless Bluetooth Trackball Mouse pairs easily with Windows and looks great next to the ProtoArc keyboard, creating a cohesive, stylish desk setup. The trackball itself isn't bad and provides decent control, but it does require frequent cleaning to maintain a smooth experience. I got it as an alternative to the Logitech MX ERGO, but unfortunately, it doesn't quite match up in terms of precision and overall smoothness. While it’s a good option for basic use, if you’re looking for something that can rival the MX ERGO’s performance, this may not be the best fit. Still, for its price, it’s a solid choice for casual use.

## 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.
