Works well for my use.
This Beurer Professional Ultrasonic Cleanser with Digital Timer works well for cleaning the pail of vintage costume and real jewelry I have that really needs it. It's pretty easy to figure out without even looking at the directions, but you may need to for precautions and water requirements, if using dish soap. I used a jewelry cleaning liquid meant for Ultrasonic Cleaners, and cleaned several pieces at a time. I have a few large pieces that will need to be done in sections, but for most regular jewelry the size is sufficient. It did a good job cleaning the pieces I experimented with. It has a timer that goes by 30 second intervals, with the highest time limit at 7:30. I'm not sure why that particular number is the magic one for this device, but some tools and other items that are particularly dirty, may need more time. Overall, it is a nice working cleaner for household jewelry and semi-small items, and I would definitely recommend it.
