Never heard of this before but a couple of lady friends have recently mentioned this product and vouch for it. Basically you spray this in your toilet before you drop log and it masks the smell until you flush. Haven't tried it myself as the missus is away so I have no reason to use it.
The latest female to spruik it to me included that the purple and pink versions are a lot better than the yellow one.
