Review on Vibrelli Mini Bike Pump with Gauge - Presta & Schrader - High Pressure 110 PSI - Portable Bicycle Pump for Road, Mountain, BMX Bike Tires - Mounting Bracket Included by Edwin White

If you're a cyclist and need something portable, this is probably your pump. Size and features are well thought out and well finished. BUT it is very small. I don't mind extra pumps to maintain portability, but you need to do 30 pumps / 10psi. I was fine with that, too, but the tube is so small that when I was inflating it quickly (because it was taking too long) I broke the valve stem on the tube. Yes, I was a little eager, but not funny. So now I have to return the pump and buy a camera. If you ride your bike that much, stop being nice and just buy a floor pump.
