First time WayFair purchase.

Ive only had this for two days. I noticed today something looked a bit odd, not sure how it was possible but maybe the weight of the TV on top  (I checked and read everything before I bought this so it can easily hold my 43 TV) but I touched each and every leg and the back one was loose, seemed to me within a day the plastic just snapped or shifted off. Anyways its a good unit if you get good pieces that go with it. Other than that I have to keep hoping this thing doesnt collapse one night. Sigh
