I just bought a MX Revolution (used) first time I ever buy something used, never doing that ever again. Doesn't even work. I've tried everything on Logitech site. I came too the conclusion the battery is ****ed. Now I have to find a way too open it.
True, I could return it. Thing is the *******, blacked out the S/N and crap 😡 what a waste, $60 down the drain 😡
I learnt my lesson, always buy something new.
I've even tried to use it on my parents Toshiba laptop, still wouldn't do ****.
Honestly why can't Apple make a wireless/bluetooth mouse like some of the MX's be way more comfortable for the hand.
