So far soo good. Works well, even on old shoes (9 Years old) that haven't been cleaned in years. If your shoes are destroyed, don't expect miracles. As far as i can tell, this product works best on newly soiled shoes. The longer the stuff sets, the harder it is to get out, thats just how it goes in general.

Overall, im happy with the product. Everything is good quality and the product works well, the Reshoevn8r videos seem to be accurate representations of what you can do with the product (just don't expect to get their results without the extra work either, like repainting/de-oxidizing soles, etc).
