My experience, which I have done this with the pump are rather positive. So, an average tire is inflated by a trekking or city bike with a few strokes on 4-5 bar. If you want more pressure must be a bit effort) you have to use some force to join 6 bar. 7 bar are almost no longer even possible. I have indeed managed to inflate a tire once so far, but I had to put my entire body weight (over 100 kg) in the pump. I do not think she can stand it, if you do that often with it. For the plastic handle is then too cheap.
Conclusion:
A good pump for petrol normal cyclists.
To 5 bar good to use.
The manometer (pressure gauge) appears to work precisely and easy to read.
A star deduction is available for the slightly too short hose.
