The pump works great but it can take a lot time/effort and there are times when the co2 is just a better solution for getting you back on the road efficiently
Co2 = lazy mofos
Pros: This is my first mini pump, but I was surprised how powerful it is; it takes less than a minute to get the pressure up to my typical riding pressure/firmness (thumb test -- I normally run about 95-100 psi); it seals easily and well to both threaded and smooth valve stems; good grip, so it can be used without bending/breaking the valve core; handle is big enough to use without fear of pinching my palm; fits easily in pocket -- 180 mm long; works with both presta and schraeder -- only takes about 30 seconds to switch back and forth; cost only $24 on Amazon; can be attached firmly to frame if you choose to do so (but the mounting clip fits a limited range of tube diameters).
Cons: Sorta porky (178 g on my scale); this one has the internal pressure gauge, the gauge is pretty useless; first time I used it it actually sealed so well that I pulled the nut off of the end of the valve core when I removed the pump from the valve stem (solved by being a little more careful about removing when done).
I might look for a lighter alternative some day, but if you don't mind the weight, this is a keeper.
Screwing is better if your core is tight. But if not, slip mode saves the day.
I went for a Lezyne road drive cfh. It has a flexible hose which doubles as a CO² head. It can be used with presta and schrader valves and has a maximum inflation pressure of 11 bar.
So far I have pumped one flat on the road and it's brilliant so far. On my trainer wheels I run approximatly 6 bar and the Lezyne was a blessing.
Since I had an collision on the bike a couple months ago I just couldn't reach desired pressures with my other pump because it felt like my shoulder was gonna blow apart. With the Lezyne it was virtually effortless.
I'll have to see how well it works with my tubs and TT wheels.

Part of the reason for the frame pump is simply to get another piece of gear out of my pockets. Especially with wet and cold weather upon us, that space is better used for clothing options as the weather can change by quite a bit on a long base ride.
They come with well made clips which go under a bottle cage.
