A nuisance

I can not understand the clerk of the other reviews, unfortunately. I have an AV receiver, DVD player, flat screen TV and a DVB-C receiver.
The remote control could be programmed in a 3-hour learning Marathon (Awkward about typing 4-digit code or via the Teach you have the original FB). But at some point the memory is full scheints. The remote control does not display a the but on. Only the trained function can not be saved. Then you have to give up less important functions and can only save the really important. This is very unsatisfactory.
In addition, the Kameleon forgets repeatedly learned functions. I now need even reprogramming several tools for the 4th time. Once I had all the functions again teach - the remote control has simply reset .. In such a situation, I have liked to see the possibility of a backup (via USB and PC or by using the same technique with which you can update the Kameleon via Internet) - but she can not.
Another point of criticism is the annoying whistling when equipped. This is a known issue and probably due to the display. Nevertheless, it is very annoying (especially the film look in quiet environments).
Another shortcoming is the strange shape. Because the battery hump the FB can never lie flat and still remembers so on a sinking ship.
I have replaced the unit now been 2 months in operation and will now by Logitech Harmony 525.
