Product review (3 stars): Nice looking, but a little flawed
It looks good and the two pieces snap on nicely. The real problem is where you thread in the tube from the dryer into the male piece (not the piece with 2 holes) that snaps into the wall mount. There's no real air lock method about it; you need to create some type of way to keep the air from leaking out.

Installation was a breeze.
It looks great.
Both pieces snap together very nice.
You're on your own to figure out how to mitigate the air gaps from the dryer's flex tube inside the male end.
