Product review (3 stars): Works as designed, cheap construction.
This item does the job it was designed to do, but the construction of it leaves much to be desired.

The metal used in construction is very lightweight and there are many places where tape is needed to prevent exhausted air from leaking.  It also had a couple of very sharp edges that could have caused nasty cuts if I didn't inspect and cover the edges with tape first.

Installation was simple, although be aware that you may need to extend the vent coming out of your dryer by a few inches and be sure o have some high temperature flu tape on hand.
