For us, this is the baby listening IDEAL! after investing in two plays of the baby BABYMOOV brand (the last high end) that did not work here, because too much interference for a pb with the load and for each other, we decided with the using customer reviews to switch brands for a final attempt. The operation of this unit is very simple, and quality at the top: great sound, no interference, good battery life of the receiver if we remove it from its base, we use all the functions (temperature about which to put pajamas baby, melody and pilot on hold a bit in the morning, and intercom to speak). Initially the intercom was for us a gadget but in the end it is a tool become indispensable for us who live in a house Floor: eg tell the big brother who returned in baby's room out to let baby sleep, tell the dad who went looking baby waking to remember to take a small vest in the cabinet to ask the dad who remained down if the blanket is not in the garden, etc. etc. The 6 melodies are very soft and pleasant. Only the pilot is very low, but this is not a problem for us. For ordering and shipping on Amazon => nothing wrong with them as usual I promised myself to write reviews if I was happy with this, then here and thank you to all those who leave comments bcp because it helps me in my decision making.
