Review on KINGTOP Vertical Mouse Ergonomic Optical Wireless: Reduce Hand/Wrist Pain, 6 DPI Levels / 6 Buttons, Rechargeable for Notebook, PC, Laptop, Desktop by David Bar

Item arrived on time and in good condition. The instructions for use were clear. The mouse worked immediately, without downloads and additional settings. The default DPI allows the pointer to move to either side of the monitor with very little mouse movement. I don't have much time to comment on the battery life. But I charged it first and the blue light went out when fully charged as advertised. Which eliminates the need for reloading and speculation. The mouse is well made, comfortable to use and works with or without a USB cable. I am completely satisfied and hope that the product will last a long time!
