Compact, lightweight, functional, but with some design flaws.
This pump is extremely compact, light (64 g), and easy-to-use. The aluminum body is smooth and sturdy, and inspires some confidence in use. Be aware If you are looking for a primary pump, this is not it This pump is meant to disappear into a bag or jersey pocket until a puncture repair on the roadside, which it excels at. It includes an attached dust plug (not shown in product photo). The pump head attaches very securely to a presta valve and pumps smoothly and solidly. With a determined effort, it's possible to reach 100 PSI or more.
While the action of the pump itself is flawless, the usability design has two big issues
First, the handle on the stroker is held onto the end-cap of the piston only by the friction between the plastic and aluminum surfaces. When pumping up anything over 10-15 PSI, the force required to push the stroker (10-15 pounds of force) causes the aluminum barrel to come free and slide forward, out of place. This is easily solved by supergluing or epoxying the barrel to the end-plug, and by careful hand positioning.
Second, the pump is secured to the mount by a thick rubber band, like a Garmin mount. This rubber band passes under two very sharp plastic teeth to keep it in place. When stretching the band to attach or remove it, it's possible that these sharp teeth could cut into the rubber band, weakening or destroying it. This requires careful manipulation of the band to avoid the risk. This can be solved with a file or bit of sand paper.
Overall, I rate this pump very highly. Its insanely light weight and ease of use outweigh the need for a bit of glue or sandpaper to fix its flaws.
Thank you for your feedback.
