This is a basic pen tool that shows the tire pressure on a slide. It is quick and easy and no batteries required.
So far, for the price, you can't beat this deal. It's just a basic tire gauge, but works well and seems to be well made. I've only used it once so far though. I looked a little online and this was the best deal I could find, especially since it's stainless steel.
Works fine. In the future I would prefer the digital one for more precise measures, but for the price - this one is good as well. Plus I was missing 2 valve caps - so those came very handy
