Logitech M510 Wireless Computer Mouse - Black (Renewed) | Ergonomic Design for Comfortable Use | Perfect for Office, Gaming & Home Computing

I have five of these in the house, two at the office and my folks each have one. I think the oldest one may be around 10 years. It's a great, comfortable, basic mouse. The added buttons on the side make web browsing quicker, I use that exclusively as my Back button. The rubber grips on the side haven't gotten worn out or gummy like others do.Battery life is more than a year, I can't remember the last time I changed the batteries on the one I'm using now. It does get heavy use, as the "logitech" lettering is almost rubbed off the top.I'll also be honest and say I give these mice some occasional abuse. I've been known to throw one across the room or bang it on the desk repeatedly in frustration with whatever work I'm doing, but it still works great!
