Product review (5 stars): Decent quality.  Installed MUCH easier than expected.
I believe this will fit any dryer with a 4" duct.  IN my case, the outlet from teh dryer was inline but about 3' below the vent.  Install was super easy, and went VERY smoothly (a rarity).  It cmoes with 2 clamps, but if you are using the adaptor that comes with it, you will need a total of 4.  I just resused the 2 that were holding the old dryer hose on.  Very neat and clean, and my clothes dry about ten minutes faster (the old hose was wayyy too long and snaked around a bunch behind the dryer)
