Pros: Tested on 16" tires, fast (considering size), doesn't warm up very quickly (temps were over 80 F) (In real life, you don't need to pressurize all tires at the same time.) The pressure is accurately measured. Leave it on the original socket.) After opening the cable, you cannot simply fold it back. But at least you can hide the power plug (which goes into the cigarette lighter) in the hole, then everything breaks, it doesn't have an auto-stop function, these are not disadvantages because I knew it before buying it and it's not very important , if you don't have a digital display. (I bought a digital display.)
