I purchased 2 of these and both did not work, I think the transmitter and receiver are matched, and the other mouse shut off after 30 sec and would not come back on, so Buyer be ware!

not micro enough.

this is cheap

#1 - download the logitech drivers for this mouse combo, then use the 'Wireless Connect' tool - it'll find them and pair them back up no problem. Just make sure you don't have multiple ones plugged in at the same time.

I have one I bought almost a year ago. The battery is just not dying for the first time (with a good amount of use). Thing works great for me and I am getting one for my brother's new laptop.
