Here short my experience with the Mannesnann Saugheber.Ich have this siphon times ordered two to lift the very heavy safety glass panel of our living room table for cleaning to können.Die operation is very simple (Put lifter on the glass and lever tilt) and the suction over ausreichend.Aufgrund the fairly wide grip the lifter is easy to grip (wide enough for both hands of my wife together) and the glass plate could if necessary not only lifted but also swung werden.Leichte Konststoffgrate at the edges were present, but could be good Remove. All in all for the price a good buy.
