In intensive use, a mouse too small tired very quickly and causes cramps less to have tiny hands.
So when I saw the price of it down to 23, I did not hesitate to replace my old wired mouse (knowing that it is a product end of life) and I do not regret.
The only fault (if is is) is the sound pressure of the central wheel that double click jOperation.
Of course to get the most, once installed, you must download and install the Logitech Setpoint software.
The location for the unifying receiver in the battery compartment is a great idea. It is so easy to lose when you disconnect from the PC.
Do not hesitate, it's a great mouse.
