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.

The volume of Deathadder mice my brothers, I and our friends went through when younger due to double clicks and scroll wheel issues was absurd.

I’ve had my Superlight since their release, used every day for work and many nights gaming. No issues so far.
