Since I had to go under the wearer for several months and this has almost made me 'insane' because constantly fingerprints, dust, makeup and much more. pasted on the glasses, I decided to buy an ultrasonic cleaner because you can not every day purely snowing at the optician and clean the glasses, seemed to me a unit for the 'household' to be useful.
1st attempt: water pure, pure spectacle, 7.30min set and off we went, finished, wiped out glasses, still 'greaser' on the glasses
~ 3.Versuch: lukewarm water, a drop of washing up liquid, glasses pure, 7.30min, goggles out rinse with lukewarm water and dry with a lint-free cloth and glasses is like just picked up again by the optician..
Meanwhile well as various silver jewelry parts and CDs have landed in the device and clean came out again.
1 star deduction there are really only because the manual is kept quite spartan and a few tips and tricks to get the most would not be bad.
Earned 4 stars and a buy recommendation, (various example. Maturities, glasses holder, CD holder, and of course the pretty blue Innenbeläuchtung) for a high-quality crafted device, with some extras
