A little cheaply made but for the price you would expect. My main issue with this inflator was that it has a small motor and compressor. It took 5 minutes to inflate from 28psi to 34psi. It also heats up, which you can feel when you touch the hose. Not sure if the inflator would actually survive if I started out with no air at all. We carry inflators in all of our cars. The three gas generators found in other cars get the job done in about a minute. If you're looking for something lightweight, this might be for you. But we need something that can inflate a car tire from flat to 34psi in a reasonable amount of time without overheating.
