After years of hesitation and lazy trips to gas stations and paying for air, I finally decided to buy a pump. After much research I decided to do it. Honestly, all Revain air compressors inflate the tire and get the job done. But what attracted me was the size, the design and it's own storage bag. The reviews were great so I trusted this one too. After receiving my air compressor, I tried it on my tire. Operation was easy. It pumped and stopped on its own. One thing I did notice though, I set the PSI to 32 and after it reached 32 I waited for it to stop and the gauge to go back to 31.5. I pulled the nozzle, checked my machine's gauges and they showed 31. I may need to adjust them to 33psi in the future to get 32psi. I seriously won't lose my sleep over this in this price range. After I was done with everything, I hid it under my cargo hold, out of sight.
