Review on Slime 2020-A Dually RV Dial Tire Gauge: Accurate 10-160 PSI Tool by Farhad Cantu

Purchased 6 months ago. When it arrived I compared it to a couple of other sensors I have for accuracy. I found this gauge to be 4psi higher when it was in the 90psi range and I had to go to 120. But I figured that wouldn't be a problem, I just figured it would be high. I'm pretty sure I've only used it to check my RV's tires about 10 times. Today is bad. It's not holding air at the base of the sensor like it's unscrewed or anything. It's garbage now. I was recommended an Accutire MS-4021B digital tire gauge, which I ordered.
