This is my third tire inflator and I have to say I am very happy with its accuracy. Not only is it accurate, but you can pre-program it to stop on its own once it reaches your desired air pressure. It's small and has a flashlight (which also works when the inflator is plugged into the car's 12V outlet. There are two power switches, one for the flashlight and one for the inflator. The inflator itself is noisy, like that most of these inflatables. It also has some tips for inflating other items like balls. The 12V plug gets quite hot after using the inflator, which is common. Overall, I'm very happy with this inflator.
