If you do not want experiments to be carried out on your things, it is better to refrain from visiting this counter. An expensive thing is irretrievably ruined, after which stories began that it was a Chinese fake, that it shouldn't have happened (but it did!), that everything was according to technology and with the consent of the client, and other nonsense... The thing is ruined, the money is spent, there is no one to blame. It's only my fault that I bought into the reviews and brought my own thing to this laundry!
