Product review (4 stars): Ok, but gets linty
It gets a bit linty (if that's a word).  The lid isn't air tight to some lint can blow out the top and get trapped in and around the hinges.  Not a huge problem but it starts to look a little dirty since it and our foundation are white.  Otherwise, it seems to work great.  Curious how it will do when winter sets in.  That's why I got it, to stop cold drafts.
