I’ve got a G502 Hero. I’d heard lots of complaints about the line after buying it but I haven’t had any issues despite having it for a good few years now. I also had a M305 for something like a decade. A very simple little thing but lasted a long time. I replaced the switches for higher grade switches than factory and only replaced it because the rocker mounting for the mouse wheel tilt snapped, which I’m pretty certain was caused by a house move than any lack of quality.
