Summary: My mouse was shipped directly from China, which took about two weeks. I guess I got the last of the production run.
Pros: Sharp looking. Nice, precise tracking while it's working.
Cons: The buttons require a firmer push than I'm used to - about 7 oz according to my scales. However, the main problem is that the mouse falls asleep. I can wake it up by bringing it down rather sharply on the mouse pad. Not really hard. But I was having to do this several times a minute. I don't thin...
Summary: I like the mouse, but seeing other people having the same problem with multiple clicks being registered is going to put me buying a different replacement. This is the first mouse I've owned that went defective after just one year.
Pros: The small form factor makes it easy to pack up and travel with. I've been using this mouse for just over a year and have yet to replace the batteries, as well. I spend an average of 30 hours a week using the mouse.
Cons: As some others have reported, the mouse has started registering all left clicks as double (or more) clicks. This means that you can't click and drag anything, and often applications are opened by single clicking. The multiple registering of one click to many effectively makes the mouse useless.
Summary: In terms of the form factor, the mouse feels great. I have a medium size hand, so maybe if you have a larger hand it may feel a bit awkward because of its size. Scroll wheel feels good.
Pros: If you receive a working mouse, the tracking seems to be solid -- I am a gamer who has played in CS 1.6 CAL-IM, in master league in StarCraft II, and have played/won tournaments in League of Legends. Needless to say, I can appreciate a good mouse. You're not going to get top of the line gamer gra...
Cons: IF you receive a bad mouse, prepare to pay ~$4-5 to roll the dice again and hope you get a good mouse. The first mouse I got had a serious defect where if you moved it @ anything other than a snail's pace, it would barely budge across the screen.
Summary: I have had no problems YET, but when Windows 8 comes out, I'm sure I will. Logitech has a poor rep for driver support. It took a full year after release for a Win 7 driver to come out for my Logitech Cordless Optical Trackman. Setpoint is also famous for conflicting with various apps.
Pros: Unifying wireless receiver, fair connect distance (sometimes), good battery life.
Cons: PRICE. $40 bucks for a mouse? Logitech devices tend not to last very long in comparison with other brands. Has good connection distance, but flakes from time to time when even partially obstructed from line of sight to receiver. I bought this for a HTPC. Logitech unifying mice are the only usb wi...
Summary: I have owned 3 over a 3-4 year period (2 bought @ the same time) and all of them have eventually had sensitivity problems in the buttons - treats a single click like it was a double. This is after a year or so of almost daily (at least 4 hours a day) use.
Pros: Precise and good distance - small usb reciever.
Summary: Already had one of these bought on the high street 2 years ago, I thought it was a great mouse so when wife ask for a new mouse and I found this one at a very reasonable price I bought it, actually bought 2.
Summary: Very easy to set up, just plugged it in. This model does not have buttons for thumb control which my children complined about, however I never used them on the old mouse so don't miss them on this new one. So far battery life is good and I am still on the first batteries.
