Summary: I used this mouse for probably 6mo to a year. I enjoyed it while it worked properly. The left mouse button had a double click issue. When click and holding, it would register a double click. You can see how this would be annoying for click and dragging. Every time you click to drag a file, it opens the file. Super annoying. Logitech did replace my mouse but by the time i got the replacement, I had moved to the Kone XTD and i won't be going back.
Pros: -Smooth -Ergonomic -Weight -Wireless
Cons: -Left button failed -Corded mode is horrible for gaming because of cord thickness.
Summary: The G6 button popped out and I was unable to get it working again myself so I started a claim. Customer Service hung up on me a half dozen times before I finally got someone wanting to talk. Sent pictures of the mouse as well as my NewEgg receipt. Now 4 days shy of a full month I get an email asking for the serial #, P/N and M/N. Why would you wait almost a month after receiving pictures to ask for basic information? Absolute nightmare.
Pros: 4 side buttons macro recording is easy with Logitech Software solid feel in the hand
Cons: G6 button popped out after a year of use warranty is a pain to get resolved
Summary: Buy something else.. not this or the G700s
Pros: Great comfort and functions.
Cons: Will break and double click issue on left mouse button defect has been confirmed by Logitech tech support. Its designed to break just out of warranty. For the price, and service I received. Look elsewhere
Summary: loved logitech until i had to deal with their support... eew...
Pros: Perfect right hander 4 buttons on the left side is awesome not TOO many buttons just enough to play with though not an FPS guy but the sensitivity features are cool the mouse ACTUALLY registers as a WIRED mouse when its plugged in, and a wireless mouse of course when not. Unlike an xbox controller that is just a wireless controller charging.
Cons: 2 YEAR MOUSE AT BEST!!!! YUK!!! bought this mouse because i loved it... and the stories are true!!! right after the 2 year warrenty is up goodbye right click... it will give out on you FAST as that warenty falls off. and there is nothing logitechs support will do with you after that. buy a new 100$ mouse. you better off buying a razor for 45$.
Summary: Bought 2-10-2011 / Died 11-11-2014 --- It started jumping all over the screen and the driver stopped detecting it. Then I noticed the lights would blink all red every 10 seconds or so. It is sad that the more you spend on a Logitech product the shorter the life span is. Was a great mouse while it lasted as long as you kept the DPI under 4000 any higher the stutter and acceleration was notable.
Pros: Comfortable, accurate, lots of buttons, high DPI, good driver support
Cons: Fragile, short battery life, high acceleration at high DPI, stutters, lag when connected through a hub
Summary: It works perfectly and it's an actual original Logitech manufactured part. You have to use the syncing software(leaflet included). If you don't have the software, go here and choose your OS/etc.(worked as of 9/1/14) http://www.logitech.com/en-roeu/support/11201?section=downloads&osid=23&bit=64 The download is quick and tells you exactly what to do. Don't plug anything in until then.
