This is a promising idea - take the efficiency of a track pump and shrink it. A teeny footpad and a flip-lock pump-head on the end of a 6in hose are both very neat and fold away tidily.
With the body divorced from the valve by the hose, you can gaily flail around while pumping without the fear of ripping the valve off. But you'll be jerking away for quite a while, as its inflation duties aren't exactly gutsy. The pump sits straight over the bottle cage mounts, rather than out of the side, as with most others - sacrificing a bottle cage - although it can be mounted anywhere on the frame with the supplied zip ties, and it's easily small enough to hide inside a CamelBak if you need to.
