This review is a warning to customers to check their parts before leaving the store. I bought two sensors on 12/22/2025. I only used one, which was the pressure sensor, and I did not use the temp sensor. I never took it out of the box, not even to look at it (big mistake). On January 2, 2026, I took the sensor back for a refund. I was told it had been used and could not be returned. I told him it was never used or opened. He showed it to me, and it appeared to have smudges on it. I did not use it or take it out of the box because it was not needed. I returned it in the same condition it was sold to me. It's the first paid lesson for the New Year. Check your boxed parts before leaving the store. Even if you don't know what you are looking at. read more
