Review on Faucet water heater with display by Danuta Py ᠌

I am buying a third similar water heater. The very first one worked for about a year (with work only on weekends in the country) and knocked out automatic machines, smoke went out from under the glass of the temperature indicator. When I bought this one, I immediately smeared the display frame around the perimeter with sealant, maybe this malfunction is laid down so that moisture gets there
