Review on ❄️ Winter's Pressure Polycarbonate Accurate Connection Tester for Comprehensive Measurements & Inspections by Michael Lucas

I bought a brand new one locally and it doesn't read more than 5psi. Done at 30psi and still reading 5psi. Not impressed. I will try a replacement. Update 12/19/15: The first sensor either fell down or was damaged during transport. It turned out that the white metal sensor inside was bent up/out due to damage, preventing the needle from getting past it. It was very difficult to see the damage in 3D when you can actually only see 2D when looking directly at the sensor. It was only when I put it back in the box that I saw that the box was damaged, which suggested it might have something to do with the malfunction. It was. Anyway, the dealer gave me a replacement and the second one seems to be working fine.
