I bought this pump, as I feel CO2 alone is too risky. I ride alone alot and wanted something that wouldn't run out of air.

The road morph is easy to use and plenty fast. I can get to 120PSI without any more effort than my floor pump at home. Sure it is slower than CO2 but I can still inflate my tired from flat in under a minute. I have many times used it to top off my PSI before a ride rather than going back to the garage for the floor pump.
