Product in accordance with the description, very easy to install and perfectly fulfilling its role. More risk than baby gets stuck fingers or locks himself in a piece once slammed the door. Produced by contrast rather large: 12 cm in diameter and 2.6 cm thick. Foam seems good quality, that is to say that does not crush, does not readily cup. Positioned on the edge (side door), height to prevent baby grabs, this door lock is perfect. I recommend.
