Today I tried it. I was üeinschaltenberrascht really positive. With a few strokes my cross bike tire was brought to 5.5 bar. Without any effort. The pressure gauge is nice to read. The scaling is in Bar and PSI. The target pressure can be marked with a yellow flag on the pressure gauge. Here is also the only weak point that I've found. The flag is very easy to move, so that it is guaranteed to move to the next use even. But anyway it is sensible always first read the pressure specified on the tire. I am convinced that we can also bring to burst the tires with this pump, so strong it is.
