TNITRIBRain Sensor Hygroscopic Discs Replacement - Repair 1 Sensor Compatible with All Hunter Rain Sensors, Mini-Clik, Rain-Clik, Solar Sync

Easy to install less than 5 minutes. Happen to rain the next day and it shut down the sprinkler system just like it was suppose to. Saved me from buying a new sensor.

Delivery was quick. The parts meets the orignal manufacturer requirements and works as expected.

The discs may work fine with others but I could not make it work with the Hunter sensor. I tested the unit before and it is transmitting. However, by using the new discs, they are: too thin or we need more. The replacements are 10 units, the original Hunter has 8. I tried a few combinations, no luck. There are several reviews for the Hunter sensor with the same issue.

Discs do not work with Hunter Mini-Clik. Discs are much thinner than OEM Discs and do not expand enough when wet to open the circuit. Although there are 10 discs provided vs. 8 that are in the original product it is still not sufficient to function properly when wet. Confirmed with another customer they had same feedback,

The cork washes are a bit thinner than the originals in the rain sensor. Hence, I needed to use an extra from the old set. Yet the sensor does not cut water fully closed and soaked with water
