Product review (2 stars): Did not work for me - only 1 side is adjustable.
This did not work for my purpose.  I was hoping it would attach to my dryer and the wall and eliminate the space the traditional hose takes up.  Only 1 of the vents on this is adjustable.  I'll provide a picture of my wall and dryer vent later so hopefully it will help you understand if this will work for you.
