A very high-quality component, very good fit, great reliability in measurement, it keeps the reading of the (maximum) pressure until the valve that releases it is pressed, it has a very useful thick rubber that protects the instrument.

It doesn't fasten easily, you lose air, you put air back in, it doesn't fasten to the valve and here we go again from the beginning. It doesn't...

Masterpiece, simple, precise, good construction. I like that it doesn't need batteries, so I can be sure it will always work.

I preferred the analog over the digital ones because when I need it, I won't have batteries. It measures accurately and has a valve to release pressure. Every time I needed it, it worked perfectly. I think we should all have one of these in the car.

Very high quality and sturdy construction.
It has been compared to a professional wall-mounted manometer and the difference was +1psi at 40.
Certainly, it is not an official certification but it was the best that could be done.
For anyone looking for something reliable, especially for motorcycle use, which is also my main use, it is worth 110%
