Product review (5 stars): Great for getting dryer closer to the wall.
Great product,  I had limited space to install the dryer next to my wall.  This eliminated the dryer vent hose on the floor and now the washer and dryer are the same distance from the wall. (I did have to cut the excess off with tin snips due to the exhaust holes being very close together but that will vary based on the brand of dryer.  Mine was on a pedestal.)
