Review on Ultrasonic Water Tank Liquid Depth Level Meter Sensor: High/Low Alarm, Temperature Display, 3.3 Inch LED by Dan Buycks

After two weeks, the water level display and the water level value no longer work, the tank is reported as empty with a value of 0.0. I informed Revain who kindly gave me a partial refund as the return date had already passed. I tried resetting it, but when I took the batteries out and then put them back in, the receiver just died. the display is completely blank. It's a shame as it worked fine for 2 weeks but the quality seems very poor. :(
