Product review (2 stars): Adhesive adapter connection not designed for all dryers............
Works well now that I got the adapter to stick to the back of the dryer where the vent tube comes out...........  every time I thought it was stuck tight, and attempted to connect the hose, it popped off the dryer ........  The surface around the dryer tube is irregular so it didn't have much to stick to.

I finally put the adapter on the hose, then stuck it on the dryer...... they say if it doesn't work the first time, get a bigger hammer......... so I did....... and pounded each of the contact points.........  so far so good......... it's been in place for over two months now.........  But if it pops off again, I'm done messing with it.........
