Where has it been all my life? I've been a professional bike mechanic and racer for thirty years, wish I had had this many years ago! A fast e-bike, a trailer and an electric mountain board are currently in use, all of which require proper air pressure. This unit easily topped them all (8 tires) in five minutes with accurate pressure and looks solidly built. Haven't done a full pump yet, let's see how it copes with that. Not too heavy to keep on board the e-bike, I carefully tucked it behind the case liner to hold the weight. A bit heavy if you're carrying it around for non-motorized touring or day trips, but the convenience and quiet make it worth considering, especially for touring! I would take it with me if I were still driving without an engine. I like the screw style a bit more than the lever type because the cam on the lever type wears out over time. The only thing I would have liked was a soft hard case instead of the unlined nylon case that came with it. At some point I'll probably look for it. Right now I'm a bit preoccupied with surviving - we live just a few miles from and are surrounded by one of Oregon's deadliest, frighteningly fast fires. I am preparing for the evacuation. EDIT 3/2021: still running! Winter tire change was quick, pump runs like a champ, 0-50psi X2 for 5 minutes each, memory and autostop work great.
