This baby monitor is simply a marvel !!! Immediately tried, once adopted! We had a baby monitor rather low end, bought at Leclerc and it was a disaster! A strength of despair and LR3 batteries 12 in 3 weeks, we have opted for quality ... Philips Avent proves once again that sometimes invest a little to have a product worthy of the name. The device is easy to use and the handling is quick. This is certainly only two days that I have but I'm already bitten! You can hear everything, the smallest baby noise can not escape. In short, a product that I recommend!
