I have also written to AVM. Back came a world of text blocks, marketing blah, but really robust conclusions, solutions or something tangible was not there.
In the meantime, it looks like that the traders who get the items once in homeopathic quantities, sell it for almost double the price (49,95 usually 85 to 99 euros). Since the trader rubs natural hands.
Because all the fuss has been going on 6 months, and AVM does not move, there is of me zero stars. Because I can not forgive the one hand and the Article 0 star itself is good (had a buy forced for 85 euros via an auction house), I forgive 1 star.
Addendum: Also, please bear in mind Buyer that the DECT can no longer switch to ECO mode when only one Fritz is Dect200 integrated into the system!. Then DECT running normally again, which in turn caused much unnecessary usual electromagnetic pollution as DECT.
