I have purchased first G602 in another popular shop (May 2015). At first I've loved it, great battery life, great performance, very comfortable.



Unfortunately my mouse has developed an issue with the middle button, it simply stopped working. I thought, well not a big deal, one time it can happen, quickly contact Logitech about warranty replacement, they have sent me another unit in less than 72 hours. Good. It all was solved in August 2016...



Today we have February 2017... 7 months later... What Yesterday happened ? MIDDLE BUTTON STOPPED WORKING AGAIN !! Without warning, without any issues what so ever. At first I thought that it was just an issue with Logitech software (I have a Logitech G910 + G13 with lots of macros, so it could happen), unfortunately it turned out that middle button died again, sometimes it will work, but in most cases I have to click 5-10 times till it will record it.



Unfortunately Logitech is mounting some extremely cheap buttons and only solution is to re-solder middle button with something more long-lasting (any button from electronic shop for £0.2 will do, still most likely 10x more expensive and more reliable that what Logitech is mounting up there).

At least middle button seems to have the same pin-out so any one can re-solder any other generic button !



Unfortunately Logitech declined my warranty request (too bad as I've paid £70 for something what didn't last 12 months and now again it failed to last 12 months, pretty bad deal if you'll ask me).



Please check forums, you'll notice that it is common that these mouses middle button is dying after short time.



I am working as software engineer so I am using on daily basis my workstation (8-10h a day) so if you are not so heavy user it might die a little later (after a year, so after a warranty period (what seems to be exactly what Logitech planned)).



Look at another brands if you are an extreme heavy gamer (if will die quicker if you'll use middle button more often than I do (in games you can often use it)).



Not worth it at all. Unless you want to re-solder middle button.



Beside that it was one of the best mouses that I have ever owned in past 30 years.
