I have that same little combo pump+inflator. I had my first chance to use it this weekend after hitting a massive pothole. The minipump is very mini and would probably take forever and a half to get to the advertised 90psi (pretty low for me at my size but rideable). However, it is handy to prime to tube and to ensure a good seal on the valve before going to the cartridge. The CO2 inflation was flawless and super-fast. It all worked out so well I'm considering getting a second one for another bike.
