Product review (5 stars): Easy to install....clothes now drying faster!
I have a very long exit for my clothes dryer, and the previous contraption I had was not doing the job even after having cleaned it thoroughly.  This flexible hose is much more convenient especially for areas where it isn't a direct shot to the exit end.  I wasn't thrilled with the tension clamps that were included.  They are on for the time being, but I will be replacing them with the screw on kind that I feel will hold the duct in place better.  Otherwise, very pleased with the product.
