The design is good, but after you take it out of the package the first thing you're told is that you have to paint it or it will deteriorate.  Well why wouldn't they have at least manufactured it with a primer or basic coating that would prevent this?  Dissatisfied with the fact that I have to essentially "fix" it before I can use it.

The design otherwise is interesting, and I hope it solves the problem I have with my dryer vent sticking open in the winter (and letting in occasional "house guests")
