Product review (5 stars): Big improvement over more rigid duct, and the tension clamps do work.
I actually love this Dundas Jafine ProFlex Clothes Dryer Duct. The one I had before was the much more rigid aluminum duct, and when I had to do some work on my dryer, it didn't fare very well. It also used the traditional vent clamps with the screw, which were also a bit of a pain, especially with the rigid duct. This duct was much easier to put on and is much more flexible. Unlike some others, I actually found the included tension clamps to be much easier to work with than the screwed clamps that were on before (just put them around the dryer exhaust and vent port, hold them open, insert the duct ends in the gap and then let go). If I ever have to replace dryer duct again, this is what I'll be buying.
