An adapter for use with the Presta (also Sclaverand) is enclosed, which is previously screwed on the valve and the valve brings the size of a Schrader valve, for which the adapter of the pump fits and is fixed to the lever. After the first strokes to 2-3 bar this is also possible with moderate effort, but it is really about sluggish. Up to 6 bar a pumping under enormous pressure to the cylinder was possible (have almost used all my weight and luffed neatly on the piston so ever what has gone). From then there was a slight hiss when valve heard: The adapter no longer holds under this pressure-tight. Thus, even under even the great effort no higher pressure is possible.
The specified maximum value of 8 bar is thus at Dunlop or Prestaventilen through the leaky adapter is not available, which is why there are two star deduction.
For mountain bikes or simple city bikes with less tire pressure, the pump would be enough, although the stability to be desired due to the moving and only one-sided bracket.
About longevity I can not say anything because I have it sent back.
Have "Sport Floor Pump Topeak bicycle pump Joe Blow" decided on the, which is a little more expensive, but without great effort and also without the hassle of an adapter screw allows very smooth high pressures.
