Review on Accu-Gage RRA60X: The Ultimate Professional Tire Pressure Gauge with Protective Rubber Guard (60 PSI) by Sandro Pierce

This is a good tool, easy to read and well built. I bought this to check the pressure on my Sportster and the 90 degree chuck makes it very easy to use. The only improvement I can think of - although not really *needed* - is to replace the rigid connection at the cartridge end of the hose with a swivel (the hose rotates, but only at the gauge end). As for accuracy, I'm pretty sure it's within a pound. I checked at a random gas station and the difference was less than a pound on both tires. The price is quite acceptable. For cars and trucks, you may not need an angle chuck. perfect for bikes.
