Battery operated, cannot perform as well as the more expensive, more elaborate, 110V alternatives.  You get what you pay for.  This unit will be just sufficient for disinfecting and superficial cleaning of a denture or dental appliance and maybe for light cleaning of jewelry, but that's about it.  Don't expect it to remove heavy stain or deposits from either.
