Hello There, actually such devices are only used in familial predisposition (already occurred sudden infant death syndrome in the first degree of kinship of the family, but then pays the health insurance) needed that is not the case with us. I learned by chance of these devices and immediately ordered one. We have it now for 8 months in operation and can only recommend it. Luckily, it had never been justified cause, but does so when Dad gets out of bed and Junior again, it forgets to switch off. For (mostly dad), it is also a certain degree of comfort to know that the mats are there, is best known as our Junior moved from the bedroom to the nursery it was good to know that there's someone watching ;-). The batteries last for now from the first day and show no signs of fatigue.
We would buy it immediately, one (s) yes creates to so much stuff because the 80 euro even more damage.
