Entäuschende pump

In August 2013 I bought this pump. I have used this pump about 30 times and had after some time the problem that the pump only with rapid movements built pumping pressure. In December 2014 also, the pressure gauge has adjusted its service and the air pump is now no longer usable. For an air pump in this price range? Then maybe a cheap China air pump because I get 3 pieces and the hold probably longer than this pump.
1 point must be one and a 2 I give for one year, the pump has kept .. I'm going to this pump
certainly not buy again!
