Review on Ultrasonic Cleaner, Jewelry Cleaner Portable - 600Ml 50KHz Low Noise Ultrasonic Machine For Cleaning Eyeglasses, Ring, Jewelry, Watch Chains, Retainer, Razors, Dentures Combs (UTEN-Black) by Ivan Gee

This wasn't bought for the advertised applications. I'm involved in graphic arts and and often use 'old fashioned' ink pens. The pens work beautifully when they're kept clean. Occasionally, though, the ink hardens up and the pen can be the devil to get to work properly. When the Uten arrived, I mixed a little Koh-I-Noor pen cleaner and water in the tub and put a dirty nib in it. When I turned the thing on, clouds of old ink seeped out of the point. I'm pretty impressed. It's about the size and shape of a brick - which plays to my ideas around professionalism. It fits neatly in corners with little of the wasted space I've found in the design of other ultrasonic cleaners. Here are the quibbles: it has a programmed run time of 5 minutes. I'd prefer that to be longer (it's So Much Trouble to tap that start button one or two more times). That and maybe a removable basket would be nice because the ink tends to make some pretty murky water. Again, for the purpose I bought it, it performs surprisingly well!
