The brand is really not important as it fits more into the no-name brand category of smallish size ultrasonic cleaners. This one is 750ml volume and only 5cm deep so meant for smallish items. They all use around 40-42kHz sonic waves through water to do the cleaning.
So far I've only cleaned a dirty fountain pen and a 60 year old safety razor. It did a good job on both and the fountain pen has no traces of ink left, and the razor has its adjustment rings turning very easily now.
The razor was previously cleaned by hand and polished with a Dremel but if you look carefully at the video you'll still see some clouds of gunk coming off it. I slowed the video down to 60% so hopefully it is easier to spot.
