I purchased this item because I'm very sensitive to smell. I share my apartment with two other roommates and thought it was a pretty good idea, also a pretty funny conversation starter. I gave this product 4stars because it really does work! You don't smell any unpleasant odor after using the bathroom. I left out one star because the smell of the spray is so strong it gave me a headache, and I'm in the other room now. I guess the scents would need to be strong in order for it to work, but for people like me who have a strong sense of smell, be warned that the perfume scent of this product is extremely strong!
