Review on Accutire Programmable Tire Pressure Gauge: Accurate, Convenient, and Smart by Marc Oner

Easy to use. Just click on it and after a few seconds it will beep to let you know it has started reading. Seeds are easy to get, good seal for accurate readings. The easy-to-read display stays on for about 6 seconds. Press it again at any time on the same or a different tire and it will restart, even if you do so while the previous reading is showing. It stores the pressure you put into the front and rear tires. Ergonomic design. I've compared it to other sensors and it seems very accurate and consistent in its readings.
