Ordinary scammers. I don't recommend it. We dragged on for a week and couldn't diagnose the heater. After the demand to give it back, they said (came up with) what's the matter with the control board and charged half the cost of the heater for repairs. I took it from them and took it to another service, they did it in one day, the sensor turned out to be broken, which costs a penny.
The absolute lack of professionalism of the master. A household appliance was put into repair. The necessary malfunction was repaired, and the final assembly led to a more serious breakdown. They refused to admit this mistake. In another place, it was clearly shown what the "jamb" is. I do not recommend it!!!
The opinion of a friend: professionals work, they repair household appliances well. She gave away the coffee maker and the steam iron. I didn't repair anything myself.
