Better than a courtesy flush
No one wants to leave a foul smell when using the toilet.  This works simply and effectively. A few pumps into the toilet bowl before "conducting business" and it's your little secret. I'm not sure what salt water smells like, but the scent is pleasant and not perfumey. It's not like spraying air fresheners after the fact.  It is convenient size to toss in a bag for when you have to "go" on the go.  The better known poo spray is about $10 a bottle so this is definitely a reasonable price for 2 good size bottles.
