The product is great. Being honest, it is a bit tricky attaching it to the toilet as if it even slightly wet it won't stick. But after a good cleaning I would recommend wadding toilet paper into the rim above the surface you are trying to dry, then drying it with toilet paper and a hair dryer, before sticking the target on. Once on it works brilliantly. It is proving an interesting target to both young and older users of the toilet. My youngest kept on taking visitors in the toilet to show them for the first couple of weeks he was so thrilled with the "magic" effect!!!! It has been on for over a month now, and is still working well, continues to be an interesting target for my sons, and has really improved their aim.....just what I needed. I would highly recommend this product!
