Review on Milton S 927 Dual Truck Gauge by Frank Chinchilla

The gauge on the valve stem is fairly accurate. When you remove it from the valve stem, the pressure somehow pulls the indicator back into the body, about halfway, giving you a significantly lower reading. If you don't mind standing on your head to read the meter while it's still on the value stick, it works. For those of us who are not into gymnastics or acrobats I would not recommend this product. This is the fourth tire sensor I have recently purchased and none of them have worked. I have to ask how hard is it to make a tire pressure gauge?
