Now that I have more than once by HWW expensive (> EUR 200, -) have been disappointed from several hardware stores, now I seem to have my perfect HWW found. The connection was simple and self-explanatory. The unit do a quality first impression. Who knows the big clunky HWW from the hardware store, should not be fooled by the smaller dimensions of this pump. The water pressure and the suction flow rate (with me almost 9 meters) are excellent. The much described smoothness I can also confirm. Have the pump is also mounted on a vibration-damping mat, now we hear only a faint whirring soothing ... ;-) The dry-running protection also works flawlessly, so there is no danger of hot running thanks to lack of water more. For longevity, I can not say much - the pump has more than 2 months with me in action and has brought the first without weaknesses behind "6 hours Pressure Washer-Marathon". So far I can not see any negative aspects - clear 5-star buy recommendation.
