Summary: Can't figure out why Logitech discontinued it and went to the side style front/back buttons.
Pros: Incredible battery life; Naturally easy access and use of forward/back buttons (due to top location); excellent tilt and scroll wheel; reliable battery indicator light; easy on the eyes, invisible optic lens doesn't flash red
Cons: I've worn mine out after 3+ years of heavy use.
Pros: Works right out of the box! Seems to work on any surface. Mouse doesn't have to be real close to receiver to work. Great price with Newegg offering 10 off + another 6 for special buy, and free shipping!
Cons: Would be nice if receiver stored in back side of mouse.
Summary: I bought this to replace another 4 year old Logitech Wireless mouse I was using before. I'm glad they have improved how the mouse uses the battery. I was having to replace the batteries every month or two.
Pros: Mouse is very responsive and the ergonomic shape makes it easy to use.
Summary: Looking at other mice currently but more than most likely going to get another one :D
Pros: By far the best mouse I've owned. I've had it for maybe 5 years now using all day every day and just today it broke. It's really easy to hold and the buttons blend in with the mouse making it easy access. I use rechargeable AA batteries in mine and it lasts FOREVER.
Cons: Short range on receiver. Expect about 5-10 feet before it gets a little touchy. Not a problem since my computer is under my desk.
Summary: At $20 for a wireless mouse, this is a great deal. I'd buy another one in a heartbeat. I have a wireless keyboard and mouse from logitech as well for another laptop and neither of them have given me problems. So far, I really like Logitech!
Pros: No install needed, just plug in and go. It took a minute or so but once the mouse was recognized, it's been all good.
Summary: I did drop it from about 6 feet on to a hard wood floor. The batt cover was about 5 ft away from the mouse. no probloems at all.
Pros: No miss hits for the L/R buttons in the scroll wheel. Fits palm like a glove. Whight is light even with 2 AA batts. Works up to 10 ft and no problems. Price was very cheap, newegg had a 24 hour deal with free shipping.
Cons: If there is one. Its all pro's zero cons as of yet. I
