I have a pretty small, mostly sterling silver jewelry collection.  This gel made all of my precious silver baubles gleam and sparkle like they were brand new again.  The one gold earrings and necklace set I own is also sparkling like new again.  I do have a pair of earrings that did not benefit from the use of this cleaner, so I think I was duped and the earrings are, in fact, cheap crap.  Sad.

The gel is thick like many people have pointed out and a lot of it does glop out with the brush, but you can wipe most of the excess off on the rim of the vial no problem.  That being said, there isn't too much product in the jar as the brush seems to take up most of the space in it.... however, I like having that brush and now that I know this product works so well, I will buy a larger container and keep the brush around for future cleanings.
