Nice Mouse, Good Idea, but 
2008-09-24
Well, I am a serious gamer. I bought this mouse for all the options it offers. It has great abilities, however, I noticed my mouse would skip across the screen. I tried changing the DPI, bought two different laser pads, cleaned surfaces, everything to no evail. Finally I sent this back to Amazon (great return ability!!) and bought the wired G5. I have not been disappointed going back to the wired G5.
Could have been just the mouse, but I did not want to take another chance on another wireless mouse. Made gaming accuracy go down, as well as irritating when trying to cruise the internet due to the mouse skip...

In term of quality, appearance, feeling and pointing, this is the wisest choice you ever make for having this mouse. Just one thing you need to consider is you have to charge the bettery all the time so you can switch bettery when the one your're using is dead.(two betteries are provided with the product) And sometimes when your're playing PC game, the bettery dies suddenly(it has bettery indicator on the mouse, which gives you an idea of how much bettery left), and you need to switch super fast to get back into the game. But I'm cool with it, feels like reload your gun in the game. So overall, this is the best ever you can imagine!!!!
Bought 2 - 2 Went bad due to weak design & QA 
2008-09-20
Bought two
Two went bad within a year
First one had trouble copy & paste (would erratically pick up only partial click and drag)
Second one
After 40 seconds of operation, it cuts out for a minute, (NO! It's not a problem with Fz lock).
I feel both problems are related in that the actual design of the inner mouse mechanism is extremely vulnerable to shock
I just work with these mice in an office environment - Don't remember dropping them - If I did, it would only hit the carpet
For example: On mouse one - depending on "how" you pushed to "click" would create a varying degree of results when it came to cut and paste
Basically both these expensive mice are useless and disco from my computers
I honestly would not buy another one of these guys products! Too much of a coincidence; and, the nature of the problems lead me to believe it is either a design flaw or QA problems over in China (or where ever they make these things)
Perfect for 1 year

Great precision. Great transmission range. Great transmission continuity... until now.
I had this mouse for about one year. Then the batteries started to run out about once a day. I use it as my work mouse. So, it's used for about 6-8 hours a day. So, pretty good performance really. When I first bought it the batteries would last about 4-5 days.
But, then the mouse just stopped transmitting for about 10 seconds every few minutes. Annoying to say the least. I tried moving the receiver 5 inches from the mouse. No good. I had to retire it.
It's pretty expensive to replace every year. But, I think I might just because it works so much better than any other wireless mouse.
Couldn't get better 2008-08-28
The Logitech G7 is definitely a wonderful product. I don't fancy tens of buttons in my mouse, I just wanted the thing to work flawlessly over the air, and so it does.
The grip is excellent, takes a while to get used to but no big deal. It's kinda light even with the battery on and I think it's a plus. It glides very confortably (yeah, that Polytetrafluo-whatever gaming feet really works) even in rough surfaces. My only grip about this mouse is that it works even a few millimeters above the surface, so it's kinda awkard to reposition the mouse when you reach the border of your mouse pad - far from being a showstopper.
Now, everything works as advertised without a hitch. There is no input lag, no missing clicks, no unexpected behavior. The DPI changing button works wonders (I switch resolutions a lot), the extra battery and charging dock are incredible and the reception range is excellent. I used it around 3 meters away from the computer without problems.
Finally, if you like the description, buy it, there'll be no unpleasant surprises - it's worth every penny.

Good but not Great 2008-08-17
Great wireless mouse. Comes with two batteries so you can charge one while using the other. My only gripe is that the battery life is literally just a day. You will be constantly swapping batteries every day.
Best Wireless Gaming Mouse 2008-08-13
This is the best wireless gaming mouse I have used. You cannot tell this apart from a wired mouse as far as connectivity is concerned. My only complaint is that you have to swap out the batteries too often. However, since it comes with two you can always have one charged and ready to pop in. It only takes 10 seconds to slide one out of the mouse and snap a new one in.

Logitech mouse fits comfortably in your hand and very easy to use. I would recommend to anyone.
Battery Life Too Short 
2008-08-03
I have used Logitech Mice in the past and didn't really care for them. They didn't seem to have the right feel. Microsoft Mice, on the other hand, always felt smooth and comfortable.
When I decided to buy a cordless mouse, I bought one from MS. It was great for two or three months, then it died. I returned it for a replacement and it too died after two or three months. So, I decided to give Logitech another chance.
I bought this mouse a little over a year ago. Like MS mice, I found this mouse to be comfortable. Unfortunately, the battery only lasts a day or so. After that, you get endless pop up messages on your screen telling you to replace it. If you wait too long, it dies. (Which happened to me at least once while playing a game full screen - the pop ups did not show up then.) The only good thing about this is that it comes with two rechargeable batteries and a charger. So, you should always have a freshly charged battery on hand. My MS mouse used regular store bought batteries and they were supposed to last for six months.
Personally, I'm getting sick of the daily battery replacement swap. I think I might buy another MS mouse. Even if I have to get a new mouse every few months, I think I'd prefer that. So, I vote thumbs down for this mouse.
