This product is easy to install, but pressure and temperature readings are everywhere. I had 38 psi in the front and 40 in the rear. The display showed 35.5psi for both tires. On a 300-mile ride, the temp gauge changed slightly, but it took a long time for the pressure to actually reach a cold reading. Also, due to the ambient temperature, I think the temperature actually drops on the road because the sensors are rotating at high speed. The product advertises with an accuracy of +-2 degrees. Absolutely NOT true. Probably the only thing this system is good for is letting me know my tire isn't flat. At least I think she will.
