This is a great gauge. The only thing is that its kind of hard to read the exact PSI of the tire since those markings are on the inside of the scale. But for me, the correct PSI is right on 2.5 BAR so I have no problems. The gauge holds the reading until you push the button which is nice. The button also lets you bleed pressure out if you are overinflated without having to remove the gauge. Great price at 6.99!
