To begin with, the bottom board's drilling was not centered correctly so I had to sand one end to get it to fit tightly to the side boards. Also, one of the foot pins would not go into the housing so I e-mailed the company for a replacement part. It has been two business days and I have yet to receive a response. To compensate for the issue I shortened the bolt and was able to secure it in the housing but it was not flush (jerry-rigged it so to speak). It works but is not ideal. Anyway, the unit is very nice but the two issues I had knocked the rating down.
