Nice looking out of the box. Upon installing we found the left corner won't stay together, dinky screws holding it together internally were stripped. We had to use a mending plate to keep it from falling apart. We also added 2 screws inside straight into a stud since the provided brackets weren't enough to keep it from flexing. The sides are aluminum and plastic. The back is plastic. Cheaper materials than expected for the price. Annoyed we had to repair it, didn't want to go through the hassle to return such a large and fragile item.
