Review on CZC AUTO Pencil Tire Pressure Gauge - Accurate Mechanical Air Gage (5 Pack) by Divine Christmas

I had an old gauge, I suspected it was wrong, so I bought 2 other gauges to compare (this inexpensive gauge and the fancier $30 gauge). This inexpensive gauge reads the exact same pressure as a $30 gauge (and helped prove my old gauge was wrong). -Pack so I can put one in the glove box in every car so I always have it on hand. to find out which side the pounds are on.
