my girlfriend was looking for an inflator so i bought it. i chose this one because it has a digital sensor/auto stop but the main reason is that it advertises for a whopping 4 hours of continuous use, i have a VIAIR 00073 which i really like and show it in the video for comparison, i also bought a Briggs Stratton (considered separately) and a Smashier because they look like a VIAIR and have a digital sensor. lots of inflators and I really like it, the digital gauge is pretty accurate (less than 1psi difference to both my manual gauges), the auto stop works well and stops at about 1psi. smooth and stable at 35psi, no bouncing, the tip feels cool even after 2 minutes of use, just like VIAIR, it's not too loud and as you can see in the video the display is bright enough to read in daylight . it looks modern, looks better compared to the industrial design of VIAIR my friend I bought in May. I don't like this style anymore. I haven't tested its claim of running continuously for 4 hours without overheating, which I doubt. However, the tip and body of the cigarette lighter don't feel hot after a few minutes of use, so I hope it will meet its needs and last a long time.
