I bought 5 in the last year. The first three are still going, these last 2 bought in the last 2 months have been really poor quality. The first one the mounts for the wheels warped and dropped the whole thing on it's side, the bottom was then warped so bad as to not keep it level with the wheels off. It was being used for children's clothes. and diapers. Sure the three drawers were full but it was still less then 10#'s TOTAL. That was enough for the bottom to warp and the wheel mounts to give way.

The second the bottom also warped, the wheels won't stay level, and even flat it still wobbles.

The older 3 that I have from a year ago are ALL going strong. I don't know what happened with the pre-holiday batch, but they are garbage. Sterilite has always been great for me since I was in Highschool, and I have literally HUNDREDS of their products, but these latest drawers were not up to par.
