Summary: Gets the job done in small compact size
Comment: I'll be honest: At first, I was a little skeptical at the durability and pure functionality of this bike pump. However, once I received it and saw it's potential, I now take it with me whenever/wherever I go biking. It's not only simple to figure out/use, it also clips on nicely to your bike, and, on a side note, looks pretty cool too. Now I can bike everywhere in the mountains and not have to worry about a flat. The build quality is very high and I can see this lasting me a very long time. If you want a portable, high quality, and highly useful bike pump, this is the product for you.
Customer Rating: Summary: Bike tire pump
Comment: I actually haven't had a chance to use this. It's a great thing to have as an accessory to your bike. It was a great price and I'm glad we have it when we need it.

Summary: Topeak Mini G MasterBlaster Bike Pump with Gauge
Comment: Great pump for the price. Will pump up to 120 psi with realitive ease. The gauge makes it easier than most small pumps, to see tire pressure, instead of guessing. Overall-very satisfied
Customer Rating: Summary: It works, but not very well.
Comment: I had this pump for a year. While this might work well for a MTB that needs only 80 PSI of pressure, it's horrible for a road bike that needs 120 PSI. Unless you're a zen-master, you'll find it impossible to generate the power to push the air into the valve without moving and possibly breaking the valve-stem. Often I was forced to just ride with 80 PSI, which then got me more flats. It was really frustrating.
Instead buy Topeak's Road Morph, it has all the same features, but it's built more like a floor pump where you can get the necessary leverage to push all 120 PSI into your tire.
Customer Rating: Summary: Effective workout
Comment: This pump is shorter that what I'm used to and it makes it a bit of a workout when you're pumping up a big tire (I know, It's not made for regular tires, but when in a bind ....) - BUT it does a great job of moving air. I'd highly recommend it.
