The Tierhaardüse fulfills properly its purpose! But I must add my voice to a number of previous reviews, it definitely lacks a vernüftiges joint at the die, so you have to run the tube very flat on the ground while sucking, otherwise the nozzle has no ground contact. That means you must be very small either, so one does not bother. or kneeling / strong bent suck. It's annoying in the long run and lead with my vote to the point deduction. The price is great! However, I'd be willing to pay a few euros more, if for a real articulated would be present!
