A wireless mouse and gaming? The two terms never went well together, a paradox constantly laughed at by the gaming community at large. Between problems with latency, accuracy, interference, and that pesky sleep mode, the two could never get along. Things have changed significantly over time however, and in 2005, Logitech was the first company to release a wireless mouse actually intended for gaming.

"The G7 Laser features a Full Speed USB bi-directional interface which enables a full 500 USB reports per second and 2000 dpi resolution. It utilizes the 2.4GHz frequency band for smooth and reliable communication during heave gaming firefights. Dead batteries won't stop you mid-mission, thanks to a five-level battery charge indicator and twin "hot-swappable" Li-ion battery packs."

Well, when I had first heard/read articles/reviews about this new laser gaming mouse, I was thrilled to learn that its design and features were just what I needed/required. I had owned several different types of mouses (mice ?), and they had all failed to perform and/or last throughout their expected/touted lifetime. When I initially purchased and then used the G7, everything seemed to work great. Getting used to its quick responsiveness took a little while to get used to, but once I did, it made all the others I had previously owned seem like bricks. Plus, the G7 was the first cordless mouse that I had ever used where I experienced no response lag whatsoever..a great thing! The first time I picked up a wireless mouse for gaming, I was traumatized. Not only were the movements of the mouse extremely laggy, but when I was sniping, I had to constantly move the mouse slightly to prevent it from going to sleep for several seconds. Needless to say I returned that Blue-Tooth mouse promptly and bought the G7 instead. That was a little over two years ago, and today I still can't use a Blue-Tooth mouse, and while I can scrape by with my old Logitech MX700 (when it's working), it too would still go to sleep when I'm sniping.

Unfortunately, however, the battery life of the G7's twin 'hot swappable' (2 hr. quick charge) battery packs dwindled quickly with daily use, and eventually I could only get about thirty minutes or so of use out both batteries...having to quickly 'hot swap' during online gaming. Subsequently and just recently, the mouse just simply died altogether. I guess that two years of daily use is not too bad, but I'm one who expects to get a lot more from an item...especially from one which was one of the most expensive on the market at the time. 

Suggestion:

I you're an avid online gamer and are thinking about purchasing this particular mouse, then just please keep in mind that the G7 will probably only last about two years with daily use...probably the reason why this mouse has been already replaced by a couple of others within Logitech's lineup. Although the G7 is light and quick, feels comfortable, and is cordless, the battery lifespan remains its only draw-back and this same problem has been confirmed by other gamers via online/ingame chat...as they too are always complaining that their G7's battery just died.
