Bike tire pump 
2008-11-02
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.
Topeak Mini G MasterBlaster Bike Pump with Gauge 
2008-10-08
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
It works, but not very well.

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.
Effective workout 2008-09-18
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.
Missing Parts, Bad Instructions 
2008-09-14
My Mini G came without the 2 plastic pieces that attach to the pump, one side for the presta valve, the other for a Schrader Valve. I called the company and they sent the pieces. Not sure if they're the right ones cause nothing fits. The instructions is one picture. I should have returned this right away, now I'm stuck with it.
A pretty good little pump. 2008-08-29
Fold-down foot rest gives you floor pump leverage. Hose means you lower the risk of ripping the valve stem as you pump. "T" handle for maximum leverage. Dual head works for both Presta and Schrader valves.
Decent Pump 
2008-08-26
I purchased this pump to attach to my bike for emergencies on long rides, which I was able to do with no problems using the included clip. It takes a LOT of muscle to get it up to the 120 PSI required for my road bike, but bikes that require lower pressures aren't that difficult, and it's better than nothing if you're stranded somewhere with a flat. My only complaint is that it is a little tricky getting the pump attached to a valve stem without losing any air.
Work great for the price, not too hard to use 2008-08-17
I got this bike pump to use with an old mountain bike I had not ridden in years. Maybe serious bikers wouldn't like it, but it works great for me (though I have not attached it to the bike, so I can't comment on those issues mentioned by other reviewers). I don't know if the gauge really works. It may, but I did not really look at it while using the pump. I found that my tried-and-true method of feeling the tires and then testing them out worked perfectly well. It may be a bit more difficult to use than the type you put on the ground and pump up and down, but for anyone healthy enough to ride a bike it should not be a problem. Also, I love that it is so small and compact!
Works well but takes work for high pressure. 2008-08-15
I picked up this pump because I was in a jam and needed a frame mount pump on short notice. I would have preferred the Road Morph and I ended up paying Road Morph price for this little thing. But alas.....
I've used it twice now on my commute. Once on my rear when I noticed I had a slow leak when I got to the office and once on the road when my buddy's tire took a goat head. The pump has worked great and the gauge works just fine. I can't verify the accuracy of the gauge, but ballpark is good enough for me. The dual pump action is a nice touch, but the result is after about 60 psi it takes more effort to push and pull the handle. After about 80 psi, I resort to using my whole body weight to push the handle in until I get up to 110 - 120 range. I only weight 130, so it definitely takes using my body and not just arm strength.
The switchable thing inside the head is pretty standard for little pumps, but I try to leave my mine setup for Presta. Another option for Presta users is Presta/Schrader adapters. In fact, it's smart to have some of those on hand as most gas station hoses are setup for Schrader.
I also carry around a little Schrader hose when I'm on the mtb and that gives some room for pumping on the trail when the ground might not be even.
Overall, the pump has done what it's supposed to do and done it well given its size.
Even if you don't get this pump, get a quality pump and not the crap they sell at x-mart. Those x-mart pumps can maybe do 40 psi if you get the "nice" one. That's enough for balls, kids bikes, and enough to limp a mtb home but isn't enough to even limp by on high pressure road tires.
The Road Morph and Mountain Morph are better and only a few dollars more. I would spend the extra money for either of those. The caveat being those are longer pumps. So if you need something smaller, the Mini Blaster G will suffice but will require some effort at higher psi.
Handy little pump 2008-08-04
This is a great portable pump. Small and light. The dual action is great and it can pump up a low tire with relative ease. Definitely a must have for long rides.
