There was a sale on the SuperPista Digital Floor Pump. While I had a perfectly operational pump, the idea of a pump with a gauge that was accurate and had a reliable pump head was attractive. I bought one since I have multiple bikes in the garage and with the new wider tires and lower pressures in use having an accurate gauge was a good idea and could save time.
The Hiro chuck was a disappointment. It's actually just as finicky or maybe even more so than my older pump heads on the cheap pumps. Here's the deal, when you press it onto a presta head, you have to get it precisely correct. Push it down too far, and the lock won't activate, leading to frustration. Push it down not far enough, and you will get leaks just as with any other pump.
The digital gauge works, and while it reads a consistent 3psi lower than my trusty Topeak Smart Gauge, I can deal with systematic errors, and of course have no way to tell which one is off by 3psi. (I just opt for the higher number, since under inflation has worse consequences than slight over inflation)
So now my inflation trials can go either way. I'll start by grabbing the SuperPista, and if I get frustrated I switch to one of the older pumps. Not the end of the world, but I don't think it's worth full price, or even sale price to get this nice pump unless you have so little room at the spokes that you have to have the Hiro chuck.
