The G502 is a good mouse, but the left button tends to not work well after about 5-6 months playing WoW.
I use it to look/turn and constantly holding it down causes it to stop sending the signal until it’s released and pressed again. I’m on my 3rd one in about 2 years, but the price has come down a lot.
I keep buying them because of how comfortable and light they are. I even bought one for work instead of using the CAD mouse they supplied for that reason.
im running the razer naga trinity didn’t even know there was a left/right wheel click lol. mine has it but it just seems to scroll up or down when i use them. not sure if you can program it for in game stuff.
it has minimal buttons otherwise and comes with side buttons if you want it comes with i think 3 sets. you can swap out via a magnet.
