After months of seeking solutions to stop bedwetting my 5 year old son, with this object, this problem was solved in 15 days. Some accidents happen again but compared to the beginning, there is no comparable measure. It is very easy to use thanks to the bracelet-type watch and the child into the habit of getting up when he feels the pee come because he is tired of being woken up all night by the alarm (which wake the whole family by the way)
