It was possible to pay only using the QR code by photographing it and only through Belarus Bank, Priorbank and Belweb did not see any information in the QR code.
The water from the vending machine is excellent. There is no pungent smell like from the tap and the taste is completely neutral, without any aftertaste. The kettle is always clean after using the water, without scale and plaque.
But! If you leave money in the machine and distract yourself, after a couple of minutes the account is reset and the money is burned. This is an unpleasant moment, to put it mildly, especially when you learn it from personal experience😅
If you are as picky as possible, you can improve the machine by adding a bill acceptor function, not just coins, and a change delivery function. So far, the machine accepts only coins with a face value of 5 kopecks.
