Great price, especially if on sale. There's more than enough CO2 to inflate my 700 x 28C Conti GP4000SIIs, there's CO2 left over at the end even when I try to empty the canister. In previous orders, the cartridges came wrapped in a thin layer of insulating EPS tape, which I think is a great feature. But the latest order came without them, so I've rated 4 instead of 5 stars.
This pump is one of the best purchases I have ever made. Works flawlessly and fits into a back pocket. It is so light that I take it with me in my back pocket on every ride.
