Title: Loud but effective
Review: I purchased this ultrasonic cleaner to help me keep my precious engagement ring clean. I bought it on the advice of the jeweler that made the ring. If you clean your jewelry with a little bit of jewelry cleaner and then stick it in the sonicator, I think you will have better results. I always use it on the longest setting, 480 seconds, but there are lots of other options. I also used the machine for my fiancee's watch after he spilled ranch dressing on it and the watch looked a lot shinier. It is pretty loud though. I keep it in the bathroom and I could hear it in the living room, with the TV on! It's a good, compact size, and most things you want to clean will fit in it. It comes with a watch stand to keep the face of your non-waterproof watch out of the water. Overall, I feel like it was a good purchase. I've been using it weekly for over a month and haven't had any trouble.
