In all honesty, this is the best portable pump I have ever used.
It's small, which would allow it to fit in most bags. It even has a mount for your bike. It has a sleek design and I would even say it is actually aesthetically pleasing. The foot lever is a key part of the pump; I didn't have to squeeze both feet together against the bottom, as I have had to do with previous pumps.
The best features of the pump are the large handle (which clamps tightly against the pump itself for storage) and the flexible hose. The handle allows for the use of your entire hand and is actually comfortable to use; I didn't experience any pain at all. The flexible hose makes it so much simpler connect to the valve. If I could make any changes, I would add a gauge. But, when it comes down to it, I would just have to pump until I can't pump anymore, and it would be plenty of pressure.
