Product review (2 stars): Did not work with Whirlpool Cabrio Steam dryer - water inlet connection on dryer gets in the way. A failure for me!
Did not work for my dryer connection situation. I have a Whirlpool Cabrio with Steam feature.  The water inlet hose, necessary for steam feature, connecting to the dryer from the water supply prevented the periscope vent from dropping down far enough to attach to the vent hole in the wall.  For anyone with a steam feature on your dryer give careful consideration to placement of the water inlet hose connection and how its placement will impact the installation. This vent is a failure and did not work for our situation, it cannot be returned because the vent was cut to size. Waste of $$!
