Review on 🔧 Alien Sunshade Tire Deflator Kit - Accurate & Fast 0-75psi Air Down Tool for Offroad Adventure - Includes Case & Accessories - Deflate Jeep, Truck, SxS, ATV, RV Tires Quickly! by Maurice Cunha

The sensor is not accurate at all. When I first used it, I "aired" to 20# on the first 3 tires. The last tire showed 25# but was over-inflated. I used a digital meter to confirm, it showed 20# tires are 26.5 and 25# r 15. It's easier to just use a valve cap to push the stem in and a gauge to bleed accurately.
