Anybody here use Diamondite Bug Blocker? Is it any good?

 

havent used it just cause i havent had to... but i do like what the product says how it works, and especially that it can be rinsed off. again, this is second hand info-

also see the warning in this thread, where someone had a bad experience with it:
