This is well-made and looks good. As a CO2 pump, this works very well. As an emergency pump, it's okay, but it's too small to be anything other than a 'get you home' pump. The bracket holds the pump very securely. One downside is that the openings for the CO2 cartridge and valve aren't covered, so they're liable to getting water and muck in them.

Love this pump!!!Extremely well built and small!!Pros:Ability to use hand pump or air canistersHand pump works perfectlyCanisters are easy to use too and allows you to control air flow via the nozzleSmall stature fits in my small saddle bag (I don't like to carry a lot of stuff)Fits both schrader and presta nozzlesLightweightCan pump up to about 100 lbs on a road bike with medium effort forwards the end.Bad:It can get warm while pumping.

I tested the CO2 cart and it worked great. I will carry 2 carts. I would not want to pump 80 psi by hand. Storage under my water bottle cage works well. Could not store it under the holder for my FoldyLock.

I have used co2 inflators in the past, but always carried a hand pump just in case i needed a back up. I thought this combo pump/inflator was an elegant solution.At first i only used the hand pump and the performance did not blow me away or anything. It's a lot of effort to get up to a decent psi, but this is for emergencies and for that it would do the job. The trouble started when i ran over a construction staple on my way to work and opted to use the co2 inflator for the first time. I could not get the valve to open no matter how hard i tried, had to pump by hand and was late for work. Even when i got home i still could not open the valve, not even with vice grips which pretty much mangled the nob anyways. Unfortunately this all happened on the last eligible day for a return and i don't have a way to print the return label and mail it out by tomorrow. I wouldn't recommend this pump and as this is my first pdw product, i will probably steer clear in the future.

I pumped up 2 near-dead flat tires in less than 5 minutes with this thing. Secures to the tire well and pumps with ease. Just be sure to brace one finger on the opposite end and not try to grab it at all. I got a little overzealous and pinched the ever-living @&$# out of my finger; a valuable lesson learned. Definitely a buy, though.
