Looked really cool but... 1: The little button that actually depresses the valve stem broke and fell out before I could even do my first check of all six tires [ double on the back of the camper].2: Digital is more accurate? Maybe, maybe not. From those that I was able to verify, I doubted the accuracy of the device. I've used two other gauges that read 63psi on my 65 max tires; However, this device indicated 50 psi. Perhaps the other two sensors were BOTH wrong; it's possible but... Luckily number one [above] did that so I didn't have to worry when I sent it back for a refund.
