I am using this for couple of months. No issues. It's compact and light weight too. It may not help to use for commercial purpose but definitely worth to have in the car. For big Tyre like Volvo 245 R20 takes quit bit a time around 7 to 10mins. But not a problem. It's get heated if you use it for more time. Automatic cutoff is superb. You set the desired number PSI, it does the rest of the job. Make sure your car ignition is ON while using this device. LED light is useful during night time road side inflation needed. Little noisy, I think that's normal.
