I have read several opinions on the product before I bought it. At first I was skeptical because it had some difficulty with the baby monitor. However, I can connect with the positive only. I need the baby monitor really only when I'm over at the neighbor, work in the garden or in the yard or out at night, then I'll give up the baby monitor to the Lessor. It reacts when you wake up my children. Then comes a short noise, because I know then already know. Silent cry be heard easily. In other baby monitors I have no problems, although babies are all in our neighborhood, and all have a phon. Here I can in good conscience recommend the purchase, I have tried several Phons and despite peak prices disappointed. So buys buys buys!
