Product that meets my expectations. Attention by cons because very sensitive to the slightest noise ... so can be a bit stressful but we can then adjust the sensitivity. We must not rely on the indicated temperature monitor because there are mostly a difference of 2 or 3 degrees relative to reality. A big downside by cons: if the baby monitor can be either battery or mains, the parent has a battery and therefore beep when it's empty ... obviously often happens at night !!! Concerning the issue of product scope, nothing to say it's great. I bought it for that point to be able to go into my field (the walls of my house is quite thick stone) and hear baby in case of problems and even set to a low emission it works extremely well !!! I recommend this product for those who like materiality long range and sensitivity when baby moves a finger !!!
