Tried twice and they failed twice. This product has a defect with the top shelf. The initial product was received with a dent and 1 hole on the top shelf didn't line up. I thought, maybe the dent had something to do with it. Requested a replacement. replacement arrives, no dents this time, but now 2 holes on the top shelf won't line up. With 2 units having the same issue only worse the 2nd time, It appears the manufacturer has a quality control issue.
