I received this product promptly, and it fully met my expectations. Read some not so good reviews about similar products, and this one seemed to have better reviews.  From the construction and operation, I am 100% satisfied it is a quality product.  I bought this to stretch out one tight shoe of a pair of Rockports I recently bought.  Sprayed it and put the stretcher in for a couple days.  Tried the shoe on this morning and still very tight, so back to more spray and stretching.  Could be I didn't get the shoe wet enough with the alcohol spray, and I didn't re-expand the stretcher after the initial stretch; I'll probably try that.  If it doesn't work, it must be because of the shoe.  If you are going to get a shoe expander, I would heartily recommend this one.
