Silicon mold to help earbuds stay put???? Any experience with this?

So the podfitkit is a silicon substance that you activate and push on to the earbud while it's in-ear. The silicon sets and you have a removable custom attachment in the shape of your ear. Supposedly this helps keep the earbud in place. Any experience from you folks? I can't find any good reviews out there (mostly just descriptions of the product).
Please DON'T COMMENT ON HOW YOU THINK IT'S A CHEAP PRODUCT. I know it's cheap, but I'm not satisfied with the after-market headsets (mostly breaking down often as far as the mic and button are concerned). Just looking for a way to keep the cheap and mal-formed earbuds that come with the iPhone in my ear while I move around (not even jogging, etc.). So long as it doesn't make the sound any worse than it is with the factory headset, then great!


Thanks for your input!!!!
P.S. I have tried the rivet set already and they break too easy, read similar reviews for higher end units also.
