I have TireProtectorUSA (which is not made in the USA) and I don't know the difference between products. However, my tire sensor has saved me twice by monitoring the tire temperature on the towd. Twice I have had my toad brake engaged and the monitor warned me before I destroyed the front tires. I question the accuracy of the PSI reading, perhaps not because the unit is incorrect but rather because I have a couple of pressure gauges, the one on the home compressor is never the same as the hand held gauge and often varies from the tire sensor when reading the motorhome at 95+psi. Still close enough to feel comfortable.
