Review: Unexpectedly Good - Coming from Logitech MX Master 3S and a first time Track Ball mouse user, this product is amazing. It takes some time to get used to but this feels great in the hand. The built quality is a tad bit less compared to MX Master but at least it doesn't have the rubber coating that MX master have that disintegrates over time. Very good value for money plus the desertcart discount!
Review: Good quality and value for money - Good quality. Takes a while to get used to after using a “traditional” mouse. Glad that I made the change…

## 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. Note: this trackball mouse is not an ordinary traditional mouse.
- 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
