Product review (5 stars): Excellent piece, Had to replace vent cover for dryer ...
Excellent piece, Had to replace vent cover for dryer due to deterioration original cover,  was worried about buying for back yard due to size of unit, but doesn't look that bad once on the house.  I attached right over siding with great results.  Had to make some shims in wood to fit angle of siding to level and caulk over so wood would not deteriorate right away, but still installed in less than an hour.  Works great, went down turned on dryer and works like a champ.  If one has the plastic outside moulding they sell now, a piece of that material for shims would have been better, due to no worries about deterioration.
