Product review (5 stars): It works!
I got this because the piece of flex tubing to vent my dryer was all bent up and was a fire hazard. After we moved I couldn't get Kenmore to come out and make my vent on my dryer to the right instead of out the back with out them making a service call first, then ordering whatever parts they might need and charging me out the rear for all of it.
SO, I ordered this. Hooked it up myself. It rotates so you can adjust it up or down depending on the straightest shot to your wall vent.
