Sometimes you may forget to spray BEFORE you go...or you don't know you are gonna need the spray till you go. This spray works either way. It is best if used before...however, know that if you forget, Royal Flush will leave the potty smelling...well, royal. We love it in our house. It does have a very masculine smell.

Does the job. Perfect for a home basement. Easy to put together if you have a socket wrench. Light enough to be easily moved into a corner or a closet for storage. However there is a small amount of wobble when it's loaded with weight. It's listed max capacity is 390, I believe. I wouldn't want to test that. If I ever work up to that weight, I think I'd hit the market again.
