It's easy to use and I can tell how much pressure I'm pumping up in each tire. I use it a lot. It's a few psi less than my car, but it's repeatable and you can easily set all four tires to the same pressure. That's more important to me than 33 pounds. or 34 pounds. I specifically mentioned that I can easily read it, it's highlighted. It turns on and off automatically. Very glad I made this purchase. Also, the clip is easier to attach to the tire's valve stem (to prevent leakage) than my newest counterpart. Seems strong enough.
