Truly a poorly perceived, albeit cheap, product.  Difficult to set up so that angles square.  One would anticipate that the vertical side and rear panels are a long as the unit is tall, but the are not.  This makes assembly rather difficult.  I feel that the products description do not match the reality of set up and use.  I basically scrapped mine after my 15 year old daughter, who is mechanically inclined was actually embarrassed by the result.
