Hagerty ultrasonic cleaners-if you have one, do you like it?

[Madam Bijoux]

I picked up my Royal Asscher yesterday (I''m delighted with the job they did on the setting) and they insisted on giving me a complimentary Hagerty ultrasonic cleaner. I''ve always been scared of ultrasonics, but since they insisted on giving me one, maybe I''ll try using it. What experiences has everyone had with this brand?
