This gas generator works, but mine arrived broken. After less than 5 minutes of inflation it shut down and never restarted. The fuse was found to have blown and broken, causing part of the plug body to melt, preventing the fuse from being removed and replaced. I didn't want to risk another defective device. The block seemed to inflate to the point of annoyance fairly quickly. It was easy to use, just set the PSI you want to achieve and press the power button. The hose barb is a bit unusual to screw onto the valve stem, but it worked fine.
