Query: Worked well... while it worked.

This product worked extremely well -- that is, while it was working. After 3 months it stopped turning on when you pressed the button.That being said, it did a wonderful job cleaning channel set baguette and round stones. It really removed the grime between and left the wedding band and engagement rings sparkling like new. My husband also used to clean his glasses in it, and it also worked well on my water resistant stainless watch with diamond accents. The capacity on this cleaner is a plus.I was truly disappointed that the machine ceased working, but this time around will probably try another product with a higher average rating than this one.
