Hello PCH, I hope you are enjoying the holiday season in whatever way you see fit.
I had a Logitech v220 for 5 years or so, and I swear I only had to replace the one AA battery in it about once a year (with heavy use and very rarely actually switching the mouse off). I've been using my girlfriend's spare "GearHead" mouse, but it eats through batteries like you wouldn't believe (and it uses two AAA batteries so it adds up).
So I humbly ask for any recommendations on a wireless mouse for my laptop that has good battery life but isn't too expensive. I hope to only have to pay around $15-20.
The right man in the wrong place can make all the difference in the world.
