Seems to work about as well as any other lube I've tried. The big advantage is that it is nontoxic, biodegradable, etc. For that reason alone, I will continue to use it, even though it is not the cheapest lube out there.
I wish they (froglube) would stop making some of the crazy claims that make it sound like a snake oil. They should just emphasize that is it a good lube, that is nontoxic and smells nice.
