They haven't built a solid reliable controller since the 360. Xbone ones don't last, even the audio jack doesn't last 6 months. Elites are pathetic for the money. So many people/friends have had replacements already. Surely these things are stress tested for longer than a week!
All my Xbox controllers are fine and two of them get chucked around by my kids almost daily. To the point where the batteries fall out after the back comes off. They're still fine so maybe I'm just extremely lucky, but I sincerely doubt it's that! I find that they're very well built.
