Review on Meirun Portable Motorcycle Digital Tire Pressure Gauge with LCD Display for Home and Car - Accurate Tire Gauge for Air Pressure Testing by Jose Schweigert

Device broke on first use. I used to take pressure readings on my bike and when I placed the device on a tire's valve stem and applied pressure to get a reading, the 'neck' came off! :-(So I have no idea if it's accurate or not. It broke on my first attempt to use it. I'd advise you to find a better, more reliable American alternative.
