In order to reduce wrist pain and forearm muscle strain, PERIMICE-720 is developed to reduce the number of wrist and forearm motions. For a comfortable and ergonomic experience, the frame is made to closely resemble the form of your hand so that all of your fingers can rest easily on all of its contours. The PERIMICE-720 has a special set of movable height extenders for individualized comfort. Additionally, it has Bluetooth and two wireless 2.4 GHz connection choices for convenience.

Features:

• PERSONAL COMFORT - It comes with two extra height extenders that can be easily attached. The first extender increases the height and creates a 10-degree angle. For those who want an extra height and even more tilted position, you can expand to a 20-degree angle.
• DUAL WIRELESS MODE - PERIMICE-720 has a dual connection mode. So, you can switch between two devices, simply by connecting via wireless 2.4 GHz and via Bluetooth at the same time. Switch devices by activating one or the other on the back of the mouse.
• STATIONARY TRACKING EXPERIENCE - By moving the trackball with your finger and a tilting scroll wheel, automatically reduces the required wrist and arm movements. You can use this mouse on your sofa or anywhere, and it will provide you the stable support for your hand and wrist to operate smooth cursor movements.
