Astrid: Tar liten plats och satt på cykeln när jag behövde den. Rekommenderar att man provar att pumpa med den i förväg. Var jobbigt att testa första gången i skarpt läge.

Tim Chang: The pump functions by threading a hose onto the pump, then threading the other end onto the valve. This is a very reliable connection that allows the pump to move without risking damage to the valve. To me, this is the best setup for a minipump. All the threads on the pump were very well machined and easy to use, as long as you are careful during set up.

soldier: Appears very effective although I have not had a reason to use it yet, I am confident that it will do the job.

Alejandro Avila Muñoz: Me ha sorprendido gratamente esta bomba para la bici por su pequeño tamaño pero gran potencia. Es ideal para llevar en los bolsillos del maillot ya que esta fabricada en aluminio y pesa muy poco. Además incluye en el interior una manguera adaptable tanto a las válvulas presta como Schroeder.
No es una bomba de CO2 es una bomba de aire.

Robin: This is a good emergency pump.
Pros:
1) Small and lightweight
2) Solidly made, quality is good
3) Flexible tube connector
4) Bike mount for pump works good. Just make sure the pump is positioned correctly in the mount.
Cons:
1) Since it is so small, the length of each pump is limited so it takes a long time to fill up a high pressure road bike tire, and it is hard to get it up to the pressure you would want in a road bike tire. That is kind of a given for these small pumps, though.

I use this as an emergency pump to put a little air in the tube so I can get it mounted in the wheel. I carry a CO2, which will fill the tire up to the road bike tire pressure. It can be used by itself, but it will take many, many pumps to get enough pressure in the tire, and that will take considerable effort.

Overall, it works for me and the small size and weight are worth it.

Amazon Customer: I used it once only and it worked . I can not say anything about durability

MMMMMM: I got this after getting really frustrated with running out of C02 on a recent ride and having to depend on someone else's pump. I did my research and found this to be one of the highest rated mini pumps out there. And I agree- I really like it...it's small, light, solid, and just works. I feel a pump with a hose is a necessity when dealing with finicky, fragile presta valves, and this one's hose screws on nicely. However, and maybe someone can clear this up for me, I find I have to screw the hose on the valve first, then screw the other end onto the pump second...the ends of the hose aren't free spinning as far as I can tell, which would alleviate this problem. Otherwise, you would have to spin the entire pump around and around until it's tight at the valve, which would make it much more cumbersome. But I think this is an A+ quality pump, and ~$20 seems a very fair price. And it is made in Taiwan, where some of the best bike stuff in the world is made...not China. I've given up on CO2...I take this with me on every ride now.

C.T.M.C.T.M.: Most cyclists like me, have always defaulted to Co2 for flats because pumps are often either huge, or small and essentially useless for any manner of practical use. This pump is very close to the Holy Grail of on bike pumps: it's tiny and it can handle pumping tires over 100 PSI, without leaving you exhausted. This pump is a winner. Here are my thoughts in more depth:

1. It's obscenely small. As you can see in my photos, it's barely the length of a bottle cage when mounted to a bike. In fact, if you really want to avoid cluttering up your bike for fashion purposes, this will easily fit in the middle pocket of any jersey.

2. The flexible screw on hose does make pumping easier.

3. There is absolutely no need for a bleeder valve, just simply slowly loosen the part of the hose screwed into the pump until the additional air comes out, then unscrew the hose from your inner tube valve.

4. Yes, expect to engage the pump 150 or so times to get your tire to 110-120 PSI, but only the last 15 or so pumps are going to be at all difficult. What I do is pump in 25 pump increments. Either way, this is what you're looking at for various tires, sizes...
