I childminder and I have several "baby monitor" because I use three separate rooms for children during their nap. For 14 years, I had 4 different, but this is the first time I am pleasantly surprised by the perceived sound quality! It really looks like the child is nearby and there is no interference between devices. I can only recommend. it is true that we must plug directly into the outlet, it can, according to the arrangement, become a problem, but for me, on the contrary this is an advantage because there is nothing more irritating that the wires to tangle or lying ... integrated pilot is a plus!
