I had high hopes for this product. Easy to read display and easy to use solid brass construction. But I was able to compare this device with two other sensors. One was the old "pencil shape" with a plastic stem that pops out when you take readings and read the scale on the stem. The other was digital brand Husky. Both are always right. I get the same readings from these two sensors. I compared the TiGaAT to these two and the TiGaAT was consistently 3-4 psi different on EVERY measurement. On my BMW with 32psi and 39psi tire pressure this gauge is offered at a 12% discount. This inaccuracy is certainly unacceptable for expensive high-performance tires.
