Product review (4 stars): Too many bends for me!
I imagine it would be a fine product if you only had two 90 degree bends. Mine had 3 just to exit from the dryer plus one more to get to the wall!. I did not realize this until I got into the job. Unfortunately the bends inside the dryer were too close together for this to work as it is not flexable enough to make the tight turns I had to make and I destroyed it while trying to make it work! Had to trash it. Had it been a typical installation I believe it would have worked fine.
