Eh, YMMV. My first pro controller lasted from release until about 4 months ago. Second one is used from a friend who also had it since about a year after release and no flaws. Among my entire circle of friends we only had one person with any issues at all, and that was someone who got one of the very first batch ones with the wonky D-Pad. Sent it in, got a replacement, all good.

Might be based on region though, dunno whether the EU stock is different from say, the US.
