Review on Measureman Heavy Duty Bayonet Style Tire Inflator: Sturdy Aluminum Body, 20" Red Hose, Clip On Air Chuck, Aluminum Slide - Range 10-130psi/kpa by Otto Suarez

Accuracy is approximately 10psi. The device feels heavy, but unfortunately feels like junk for the most part. It's easy to read but not easy to use. The barrel grip doesn't hold and requires two hands to operate. The retune window is closed and of course this is my first time needing this tool. Spend your money elsewhere.
