Okay, replacement goes so quickly and easily on Amazon. DHL brand is on it and I go straight to the post office.
Third attempt is then also the last! If the machine will not work, it remains with the (provisional?) A star!
If it does then part (and I trust - anyway) it gets from me at least four stars. Promised. But for more than the great idea has to come - This requires also QUALITY !!!
SUPPLEMENT:
Improved from one to three stars: therefore - So now it is doing the part properly and reliably! For "perfect" it is not enough for the history, unfortunately!
