10" trailer tires up to 85psi in no time - check. Car tires up to 51 psi in no time - check. It seemed to me that this device is small and light. It's about the size of a liter bottle of moonshine and twice as light. I agree it's quiet for a compressor as others have mentioned. lots of air to bleed but amazing how little comes out even with my small trailer with 10" tires. Although this device looks a bit pricey, unlike the $50 junk, it actually gets the job done.
