However, we have bought five in supplementary package added. These have in deviation from the illustration shown a sticker: "Important new technology Lunix 2011 is not compatible with older versions!". Before opening I thought would our existing only two years old, but not true. And thus let this not be combined with the old. The new can not be switched with the old Fernbediehnung, but look the same.
Thus, they will be sent straight back to Amazon.
In a review I read that you asked Amazon to change the image. Unfortunately, this is not yet done. So be careful!
