Because it is not essential to have wireless phones everywhere, I opted for this product, which remain quietly placed in the room by the bed In terms of its strengths: the M110 is well made, rather aesthetics and the sound is excellent (the handset as via the speaker). Regarding what is most regrettable: the memory of the device and its display are powered by batteries (which is not very "sustainable development") and the contacts stored in memory is quite tedious. A good product dependent on these three batteries.
