What's not to like here? The Blackburn Frame pump has the usual advantages of a frame pump - simple stowage, and a big barrel for quick, high pressure inflation - and added to those a T-bar handle for maximum comfort.
It was minimal fuss to register 100psi, and the pump maxed out at about 125psi - plenty for any situation where you'd carry a frame pump. The design is sleek, and the sprung barrel (lockable for high pressure pumping)keeps the Blackburn firmly in its place. In terms of performance, it's the best frame pump here. It might not last quite as long as an HP-X, but with a lifetime warranty, who cares?
