Seems like they either have inconsistent quality or it went down over time. My 6-7 years old g502 is from a mechanical standpoint in perfect shape, I’ve just worn out the rubber sides and had to replace its feet once. I’d even say it’s seeing fairly heavy use considering I use it for both work and gaming.
Possible, it is a 20 something GB update on steam. Still quite a lot of I am being honest.
