Product review (2 stars): Cheaply Made, Make One Yourself
Was surprised how cheaply made this was. The vent on mine was crooked, looks like it was put together in about 10 seconds. Also looks like someone spilled something on it, has a sticky residue all over the metal. I am going to take it apart and just get some plexiglass and build my own. It might fit your need, but would look elsewhere.
