Review on Accurate and Convenient Tru-Flate (17-555) Truck Tire Gauge - 10-160 PSI Dial for Reliable Pressure Monitoring by Jay Aukuso

This is a great tire pressure gauge for our small C-class motorhome. The air hold feature is great because I don't have to hold the cartridge on the valve stem and try to read the gauge at the same time. As RV enthusiasts know, some valve stems are hard to reach, and this gauge gets to all six on our rig. Too many times I lost air with my old gauge and had to add more air. This sensor is the perfect solution and now I use it on my cars too! All gauges can vary slightly and I find this gauge reads slightly higher than my old gauge and pump gauge. I don't know which is correct, but all three are within a pound of each other.
