Let only the finger of this pump, I ordered two pieces and after the first use of the pistons is flown out of the cylinder of the pump and the thing is scrap!
By TÜV Süd and GS approved, my ass ... I'm really starting to wonder myself how this pump were tested.
The article you can apparently handle only with kid gloves and use as a paperweight!
Much more can and I want to write, ordered two pumps not, once and broken I think speaks for itself!
