I had a good pressure gauge which I have used for a number of years and will continue to use. I do autocross and the last event I went to was in a big rush. This required me to deflate a few pounds and it was taking too long and people had to walk around me so I had to come up with something else that would deflate faster. My dad has a similar one and it bleeds very easily so I went with this one as it has both ball and angle chucks. pump it What would have taken a full minute now takes just a few seconds. Each short press costs 1/4-1/2 pounds and is fully controlled, which is perfect. It holds the price very well and the bonus is that the movement is very smooth. It doesn't click up and down like a regular gauge, which to me means it has better internal control and prevents the needle from hitting the stop at 0psi. I use a corner post because it pivots and works very well. A ball chuck is also included but to be honest I will use it. I also decided not to pour any liquid. I think you can call it Murphy's Law, but every time I use a gauge filled with fluid to check tire pressure. The bubble is right where I should read the numbers. As liquid filled is typically used for applications with vibration (e.g. at work we have a 5000 psi pressure washer. It vibrates and the gauge is liquid filled so it has a good and smooth reading) so this is not mandatory . Finally, it doesn't come with a case, which is fine. I keep it in my door pocket, and even with my last meter, which had a case, it has never been used. The quality is very good and easy to read. I look forward to using it for many years to come.
