Two-tank cleaner for jewelry, eyeglasses, and other optical equipment, with Lo/Hi settings. I purchased this after looking for an ultrasonic cleaner. I tested it once at home and then stored it. It runs on 4 AA batteries. I have not re-confirmed its operation for this listing. Batteries and other accessories are not included. The price reflects the shipping cost due to its bulkiness. It will be shipped without the box. - Product Name: Jewelry & Optical Cleaner - Function: Two-stage settings (Low/High) - Application: Cleaning jewelry and eyeglasses - Color: White Thank you for viewing.
