Driver problems and the mouse somehow corrupting all my USB ports forcing to replug my keyboard/headset alot.

So far after a week of use it is great. Probably the best mouse I've used, and I have tried a lot. The scroll wheel was initially extremely stiff but was normal after a day of use. The sensor seems perfect, and mouse lift off is extremely low.

2 buttons including left click failing at 6 months

After purchasing this mouse over a year ago, the left mouse button has started to break down and incorrectly respond to inputs, after doing some googling it would appear that this is a very common issue for this mouse after approx. A year of use. If you don't plan on using this mouse for very long then I would recommend it, but if you plan on using it for a long period of time, > a year, be ready for the mouse to start acting up and not inputting correctly.

I bought this about a year ago and its started to fade out its gotten slower and less responsive but it is an a amazing however the there is only 2 buttons that can be programmable in-game overall good mouse but not so great after 7-8 months

Mouse left click double clicks

How do you build a successor to the best selling gaming mouse to date? This tall task was taken on by Logitech while developing the G502 Proteus Spectrum gaming mouse . The answer? Some RGB loving, obviously.

The Logitech G502 is a solid gaming mouse with a ton of useful features and excellent performance. The software lets you make adjustments that can be either radical or superficial, and the included weights are a nice touch that further improve accuracy.

Had a wow mouse from steel series wore it out. So i decided i have most all of the other g series stuff. Just hooked it up a little while ago. Pros: Software is awesome.. I had g series equipment G35 and a G15. Didn't have to install any additional software..

I have experienced many other gaming mice such as alien ware and razer but the g502 is by far the best. Overall, the quality of the mouse is stunning. Firstly, in my opinion, the most important feature of a gaming mouse, comfort. The mouse is very comfortable and is perfect for playing games.
