The pump is completely made of plastic, but the workmanship looks very robust and reliable. By double stroke can inflate large mountain bike tires quickly. Interesting for touring and racing bikes: You can reach easily 5-6 bar, something more is also possible, however, quite difficult to move. Other minipumps give already much earlier.
It works with all common valves (Auto = Schrader, Presta and Dunlop racing =). A needle for inflating balls is attending but not yet tested.
The "guts" (1x rubber seal, 1x plastic insert) of the valve adapter must each be rotated 180 degrees when going from the Schrader valve on the bike valve. This conversion is only indicated on the packaging, which many will certainly be overlooked. This conversion is, however, almost all Mini Pump with one outlet equal.
Small detail:
The hub is secured by means of rubber ring. When a pump is me this is already torn, could therefore be carried out better. In relation to the rest of this review is absolutely negligible.
Pro:
+ Reasonable price
+ Robust and compact design
+ Double stroke
+ High pressure
Negative
- Missing description about remodeling
- Hub-assurance could be more stable
