Its totally bad. Light problem with the new one. Many time auto disconnected with pc. And the wheel not properly working it stuck when rolling it. Connecting cable usb point are very loose. Surface also not good supporting rubber in the surface are less gum. Its puts down every time when I was rolling mouse faster in playing games. Right click button also not working properly. Its auto click three or many time automatically. And the button jammed while clicking many time in playing games or doing other works.
