Logitech optical mouses have one big flaw. After the first few months the sensors below wear off and the scroll becomes rough. I had the same problem and my mouse stopped working properly after the first three months. I couldn’t even return it to the vendor. Thus, the device is a waste for people who have to use the mouse roughly and those who play games on the computer.
Final Verdict: I recommend this hardware to people whose jobs consist of mostly typing and not heavy use of the mouse.
