Floor pump snowflakes?
Come on, the chuck is fine, I actually like it better than the flip kind. Press down, twist, and it's on. Not rocket surgery. "Doesn't pump enough air"? seriously? On a road bike, it's like 2 or 3 pumps to re-inflate a tire regularly, and, what...like 8 or so to inflate a new tube? First world cycling problems, I tells ya!
OP, my Lezyne floor pump is fine. Don't know how accurate the analog gauge is compared to a digital one, but I'm not losing sleep over a few PSI if it's not super accurate.
