I just received a tire gauge and was impressed with the quality and the dual pivoting of the tube. I checked the pressure readings on my other gauges, both digital and manual, and found them to be within +/- 1, with the exception of one digital element that didn't suit me and prompted this purchase. The swivel makes it much easier to use when I'm checking out doubles in my RV and then switching back to my truck and tractor. As for durability, time will tell.
