Product review (5 stars): it's great and so easy to install
Read all the reviews and decided to give this a try even thought I thought it was over priced.  Wow, it's great and so easy to install!  We had the smooth metal venting and every time anyone moved the dryer even a few inches the tape and clamps would get all messed up.  This flexible duct venting with the great plastic ends is the perfect solution and it's true, no clamps or tape needed.  Wish I'd known about this years ago!!
