Excellent product, I cannot recommend it enough. Whether you've got issues with stamina or you just want to have a fun filled evening, this spray is perfect. I used to use Stud100, but I'll be using this from now on. It works in under 5 minutes, and you don't need as much as Stud100. It comes in an aerosol spray rather than a pump, so it's much more accurate. Also, Stud100 can leave you with a bit of a funny sensation, whereas this has zero after-effects, and my wife has said there's no funny taste with it either. Awesome.
