Great little pump for road use, inflates surprisingly quickly for its size and gets 25's up to a rideable pressure without feeling like it would explode. I should have paid attention to the fact that the Pro model is all alloy and this one has a plastic cap on the shaft, but no big deal, it's still surprisingly solid and well made.
I like how this pump solidly connects (Schrader or Presta) w/ a screw-like action to tube valve. Yes it requires assembly, but this allows the important parts to stay clean. Well engineered!
First, it pumps. You will inflate your tire to proper pressure. You will also get a workout, as you do with any small pump. But it is very well built and designed the air that goes into the pump goes out into the tire. Also, with tubeless tires, I feel that the flexible connector reduces the stress on the valve which is secured to the rim.
But this little gem is compact. I finally found a pump that fits in my (compact) saddle bag!
If size is not a concern, a slightly bigger one will get the pumping job done faster. But since I do not plan on having flats often, I trade inflation workout for compactness -)!
