I tested other products of the same style but are somewhat painful to use for an adult, but the principle of this one is ideal for doors we must open frequently enough. However, it leaves the door ajar slightly but so little that it is not disturbing. It's been a little over a month it is placed and for now it fits perfectly. It perfectly fulfills its function, my child a year and a half knows very well the close, but can not open it. The distance between the two elements is adjustable which is very convenient.
