Product review (5 stars): Simple to use and does a great job
Amazon was priced significantly less than Lowe's for the same product.  The product was easy to assembly and worked well in the unusually long dryer hose installed in my house.  It does suggest replacing vinyl dryer hose with metal to avoid the risk of tearing, but part of the dryer hose in my house would be difficult to replace.  It did not tear the vinyl at all.
