Product review (3 stars): Great idea, lousy attachment to dryer.
Like the protection this gives the venting on the back of the dryer.  However, the attachement to the dryer vent at the back of the dryer could use a bit of work.  The geometry of the unit bend is great, the protection is great, but the way it attaches is very much aimed at a very narrow variety of dryer outlets.  We have LG and this could only attach loosely. Had to jury rig it to attach.
