Product review (3 stars): Leaks air out of every seam.
It fits as described, so that's the best part of this. Also, it's rigid, so you can shove you dryer against it as hard as you need to in order to get every possible mm of precious clearance. The downside is this thing leaks air out of every nook and cranny like a sieve so you better make sure you have enough foil tape to plaster it or you may as well remove it and run your dryer with no duct at all. Then you can thank the brilliant builder of your beautiful home for having no foresight when installing air ducts and doors in your closet of a laundry room, even though your house is huge.
