Product review (5 stars): BE SAFE, NOT SORRY.  Sorry is for suckers . . .
The flimsy vent hose that came with my $750 dryer defeated my every effort to attach it and keeeeep it attached, so I went on line to Amazon, found this perfect solution -- Amazon Prime got it to me in 2 days!  I guess I'm not good fitting coil hoses, so I used metal foil tape, and taped this new, STURDY, MUCH SAFER thing to my new lint trap together with foil tape and IT'S WORKING!!!  Safe, sturdy, easily cleaned out.  I live in a small apartment where I couldn't attach my dryer to a dryer vent or a window.  This still works after a year!  Still using what came with your dryer to vent it?  YOU NEED TO REPLACE IT WITH THIS DEFLECTO !!!  Soon.  Don't risk a lint fire with what you have.
