Works fine, stable. Attached correctly considers it even if the child of this door is not enthusiastic and hangs and shakes. Installation frankly some strength-consuming because it (how could it otherwise also keep) must evaluate stretched into the door frame. Anyone who has seen so far can only be this child safety will perhaps be surprised and think it was broken or bent. The frame is straight once it has been installed correctly. Installation requires some skill and some force. We are convinced of this product and can recommend it.
