Product review (4 stars): Almost 5 stars...
This apparatus works great and does all it promises.  There is, however, an issue that is so super-easy to fix that I cannot believe the manufacturers have not done it: cover the ends of the thin metal rods!  When the dryer is doing its thing, the ends of the metal rods push against the plastic which when warm becomes very soft.  My husband noticed this the very first time I used it.  As he was pointing it out to me, one of the rods actually poked through the plastic!  Luckily we had some silicone tubing which we slid over the ends to alleviate the problem.  Fix that and you get 5 stars!
