Review on Quick Pressure QP 000034 Chrome Monitoring by David West

They work reasonably well and are easy to use. Just pump up a tire, pop it and ride 10 miles. It is so easy. Just make sure they close snugly, which wasn't hard for me as I just tightened them until I could hear air and then continued with a few more turns. And I was done. Now all I have to do is look at the tires to see if they're properly inflated or not.
