Had 3 of them.
- First had a loose micro USB port
- Second has developed loose panel
- Third so far is fine
The analog sticks get incredibly dirty after one week of ownership. My blue controller was starting to show dirt on it even though it hasn't been used for days. The 360 controllers were really solid, even the one that's been on the wrong end of rage, but is still solid. Had a one of them for almost ten years now and it's still in pretty good shape. I don't think the Xbox One controllers would survive any rough play
