So far so good. I installed it and it is working correctly. I chose this sensor because of the 1 year warranty.

Considering the price I was pretty concerned about how well this would work as a replacement for my bad sensor, but I hooked it up and it worked instantly! I used it to replace my bad air temperature sensor.

I replaced my 19 year old original water temp sensor with this one, works perfectly with no issues, and now my water temp is accurate again for my pool/spa...

Looks, fits and works exactly like OEM at a small fraction of OEM price. Can't beat it ... the heater is back to normal and my system doesn't report the pool being 165 degrees any more ...
