I am wearing glasses since the first class, and I have since I can think annoyed that virtually no Brillenputztuch the plastic lenses of my glasses lubricants and especially scratch-free cleanses.
Now I just leave my glasses "sound for" a few minutes, again briefly wiped dry with a microfiber cloth and even outshine the glasses, each hinge and every little screw.
Thanks in advance to my friend for the practical gift ;-)
One should be careful, however, when the materials to renigenden. In the manual an overview shows which materials can be cleaned under any circumstances (eg horn-rimmed glasses and other natural materials), since the ultrasonic waves would cause this damage. My frame acetate (lt. Internet made of cotton and thus natural material;)) does have a little bit missing immediately after the treatment to my mind from the previous shine, but returned to normal as soon as I once briefly polished with the microfiber cloth over it.
The size of the cleaning cloth is - contrary to some reviews here - at least for my glasses perfectly adequate and big enough!
Very pleasant was the volume. Only a slight hum, more could not be heard.
I tested the unit then also times with other household items, it had old scissors, chains and other odds and ends to serve, always with the same Erbegnis: Perfectly clean!
Absolutely practical tool for everyday life!
