I was pleasantly surprised in addition to performance, the barely audible sound when pressed also by the stability that seems to be not necessarily given the first impression of the images. The thing is, however, quite large and has the focus near the bottom. Therefore this is not an issue.
Cleaning is also very easy. It takes less to rinse everything under running water than a minute and was immediately a clean device.
That one only glasses up, I think 13 cm height (Pitu Caipirinha glass is) can make under it, though could be improved but not really bad.
Overall I am very satisfied with the purchase, because I really have to get even quality for my money feel.
