Summary: Really liked this thing...on off switch was great. Wish it had more buttons and came in black. Logitech is well known for having the best quality mice and for being extremely reliable. I'm thorugh w/ MS products and have moved on.

Summary: I like it so much, especially for the 15$ rebate during these days! It is small and very very light compared with v270. It connects to mac very fast. There\\\\\\\\\\\\\\\'s no colorful light under the mouse which I assume it should have. And it is much small, maybe some people with large hand won\\\\\\\\\\\\\\\'t like it :)

Summary: Mouse works well w/ Dell D620 bluetooth adapter. Connected without any issue. Comes with everything you need right off the bat, batteries, and a neat carry case to protect it. The best part, it has an off/on switch to save the batteries.
