My son has a gold rope chain, I could not get it to look clean, I used this and it now shines like brand new. I did have to run it thru several cycles and I will tell you the water turned black from all the built up dirt. I would purchase this again without question. Highly recommend.I noticed in other reviews that sometimes it quit working or had mold at top of stainless steel interface. I suspect that if you keep running it without putting in cold water it will overheat as the water does warm up. Likewise I don’t expect to have a mold problem as long as I empty it and leave the cover off. I’ve had it one day and these are my expectations.I purchased my jewelry cleaner for my segmented lashes, Lashify. I spent hours cleaning my lashes (lash laundry) letting them soak in ETOH and brushing off the bond painstakingly and then resonating them and cleaning with a makeup brush again. I decided to buy this gem and now I run the ultrasonic cleaner with appropriate solution and the bond disintegrates to the point that I cannot see any bond on my little lashes. No hours of soaking and brushing off over and over. I spend no more than 1 hour laundering, cleaning and santizing my lashes now. The best purchase I could make on my beauty investment of gossamer lashes.I highly recommend this ultrasonic cleaner for both jewelry, cleaning makeup brushes and eyelashes. I purchased one for my makeup tools/lashes and one for my jewelry.Use a capful of the cleaner of choice for stones, metals etc and push button to start. Auto stop.Cleaning pandora jewelry that had been tarnishing. I was able to get the beads looking good again with use the ultrasonic cleaner and dawn dish liquid and white vinegar plus new polishing clothes. I had do several cycles in the machine to clean the beads to my satisfactionit's the best package because i can tell this is a 'brand new item', the way i see the electric cord is tied up, lol! i tested it yesterday, i was pleased--as soon as you pressed ON button, you will see a BLUE light inside the tank and according to the User Manual, there's a 5 minutes timer to clean an item and automatically, shuts it off. And also before you start to a new cleaning process, let the machine cool off, first. this is my first day using it for cleaning my eyeglasses using only less chemical dishwashing liquid from Melaleuca products (if you know this brand name)! i loved the petite size-- in mm: 226x130x118 (LxWxH); the tank material is a stainless steel; Made in China. i would recommend to empty the liquid after each used and dry it.Definitely got my diamonds sparkly againDidn’t find it worked well on silver
