Great pump with caveats
I got the HPG version. Much easier than other hand pumps to get your tire to pressure, since you can anchor to the ground. Pressure gauge is accurate (tested against my floor pump at home). Overall, solid pump.
Caveat 1: the hose got unscrewed near the pressure gauge and was leaking air. You can tighten it by hand and are good to go. Seems like a bizarre design flaw and scared me, but not really an issue.
Caveat 2: the pump rattles on my bike when in the frame mount. Since it is so long, when I go over big bumps, it will clatter against the frame. This was a deal breaker for me on my carbon bike. This pump now lives on my aluminum commuter, where it serves me well.
