Query: Looks great, engineered poorly

I didn't realize that my girlfriend spent $40 on this thing. She thought she was buying a quality product. Worked fine for a while and, like the other reviewers, we began having problems reassemblying the unit after cleaning. Great idea, poorly executed. It is not sturdy enough for heavy duty kitchen usage, as I used it to chop veggies virtually every day. I am now searching for a professional model designed for restaurants.
