This is a great product in many ways - size, lockability and the materials are sturdy.  However, the fact that it slots together and there are no screws holding the sides to the top and bottom ( that is done with metal tabs and friction) makes the piece have less structural integrity than I would like. I picked the piece up by the bottom legs to move it after putting it together, and the inside shelf hit the top knocking it off and the sides sprang loose from there. Wow, I was surprised. I really liked the piece until that happened. It was put together again, and I now know that it needs to be moved with care.
