Very easy to install, lasts in time, and melodies a little different from what we used to hear. Very good range, even through thick walls and floors, so it's perfect.

several levels of sound, and especially a wide variety of ringtones, very happy I recommend the product, especially as far as I'm concerned it is added to the ringtone but I could put it in one place strategic ...
Easy to install, there is a lot of choice of ringing, to each its air, its net and strong enough for people who hear badly. Nothing to say for the moment, for the longevity, it is not long enough that we possess it.

Fast delivery product according to the description. Good value for money. The fact of being able to take two receivers is practical for the houses with stage.
Easy to set up, I like the fact that I can set a different ring for each door.
