Review on AZUNO Rapid Air Down Digital Tire Deflator Kit: Ultimate Offroad Repair Solution for Cars and Bikes by Chris Tardy

Easy to set up and use but only works occasionally. Most of the time it says NULL. I installed it correctly, I look at the readings, sometimes it reads correctly, then it goes to zero and again the pressure doesn't show. Maybe I'm doing something wrong, but these things shouldn't be that complicated/fussy. I would return but the return window has already passed. I seem to have gotten stuck on this piece of junk. Don't buy this.
