Product review (3 stars): Doesn't really shorten your 90 degree turn that much over a standard unit
Doesn't really shorten your 90 degree turn that much over a standard unit from your local big box store due to the annoying metal fins that stuck out too far from the unit. I ended up having to bend and hammer the "fin" where the sheet metal is joined, then manually cut back the exhaust vent tube on the dryer in order to get my dryer close enough to the wall to be used in a stacked setup.
