I also bought this pump and everything was only satisfactory. First, the pump is not just the most powerful and fastest pump, for the price you get much better. The real problem was followed by 5 months of use for bicycles and balls. One day I suddenly had the whole bar, including handle in his hand ... The rod is apparently bolted only in one Plastikschanier inside the pump ... I wonder what the manufacturers have this only gadacht, so to mortise a crap ,
