Cleaning Jewelry with Ultrasonic Cleaners

Have any of you tried using an ultrasonic cleaner to clean your jewelry? I know they use them at jewelry stores, but you can buy them for use at home and I was just wondering if anyone has any thoughts on the subject?

I was reading online that you can clean a ton of things in them besides jewelry. I suppose it matters how big of a model you buy, but you can clean baby bottles, tools, weapons; all kinds of things. Supposedly things come out sterile and sparkling.

If you have any experience with an at home ultrasonic cleaner, I'd really appreciate hearing your take on it. I'm thinking about getting one of my own for cleaning my jewelry and sterilizing the nebulizer parts and such. If you use one, what brand do you have?
