I like the smaller size of the Mini Morph. It doesn't need a gauge at all. When I have to press down really hard, it's at about 90 psi, good enough for the rest of the ride.

The big advantage of the Morph pumps is their hose. The end of the pump rests on the ground, so I can press down hard, and yet there's no stress on the inner tube's valve stem. Riders have ripped the stem loose from the tube with normal pumps.

The last time I used it, I sort of counted along, and it took a lot more than 100 pump strokes to fill the tire. So it does take a few minutes at least. I only need it once or twice a year, so that's ok.
