It was one I bought on eBay. Not a super cheapy, but the smallest model of their line. Quite inexpensive. Wife loves it for cleaning her jewellery. Bear in mind this is in Australia. It is rated at 35 watts, 240 volts and I run it for 5 minutes with a little detergent, then rinse out and wash again for 2 minutes in clean water before drying, lubing, weighing & sorting. Word of warning. Do NOT stick your fingers in while it’s running as it will destroy bone marrow. The more powerful the more the damage it will do to your body.
