Product review (2 stars): Supplied Vent is very rigid, have H/A foil tape or a new properly sized Flex Vent on hand
OK, it's a very good idea, but I am pissed that the circumference of the supplied flex vent did not fit my dryer and no matter how I tried, the flex vent could not be tightened down on the dryer vent with the hose clamp. Supplied Vent is very rigid, don't expect it to do much flexing and it will NOT fit dryer vent at all. Have H/A foil tape or a new Flex Vent on hand.  Luckily, I had read the other reviews about people who had to tape their installation to their dryer, and I had a lot of the foil tape on hand. I had to tape the flex vent to my dryer AND tape the magnetic connection, because the flex vent is not very flexible. There was a slight gap at the top and the magnet did NOT seal completely. The supplied vent pipe is fairly rigid, it would not flex upward about the 2 inches that I needed it to.  I will try a new flex vent, if that still does not work I'll have to cut the drywall and try to lower the wall vent access. I am very experienced with all forms of construction, but I would have been better off with just a very short $6 new flex vent.
Looks like crap, for the money I expected far better. Disappointed.
