This is a 0-100psi gauge that works well with higher pressure car tires and bike tires. The hose extension is a very useful feature. The end you press onto the bar of the tire works very well and doesn't leak. It would be nice if the pressure gauge retained the pressure reading after it was removed from the tire stem. But since you have a hose extension, you can easily read the gauge while it's pressurized in the tire. I also bought a rubber protector to cover the pressure gauge. I think this is necessary as the dial face doesn't really feel solid. A nice feature is that it has a pump button. You can use this if you pressurize the tire a few psi. I compared the readings from this gauge to a pair of more accurate gauges I own. The readings were very close and certainly accurate enough for the tire pressure. Overall, the gauge is good, accurate, and easy to read.
