Product review (2 stars): Not a bad product but it is only held on and sealed ...
Not a bad product but it is only held on and sealed by using the included clear silicon (or some type of rubber) ring. Had some trouble getting this item to seat well on the dryer exhaust vent and, if I need to move the dryer, this can easily detach from the dryer. also had to struggle to connect the aluminum vent hose. Probably would not buy again.
