It is a pump and it does the job that it is expected to.
Pros: the gauge is closer to the eyes and that makes it easy to read (especially if you wear glasses). has a fairly large volume and does not require a lot of effort to fill air to 100 psi (road bikes) or 70 psi (mountain bikes).
Cons: the bevel around the gauge does not have an arrow mark and does not rotate. that feature would have been even more helpful.
