As usual lightning fast delivery through Amazon. I use the shutter to drawers and sliding doors (wardrobes) hedge against our little ones. The closures are initially quite stiff. If one has not waiting until the adhesive tightened, tearing one adhesive fasteners immediately after assembly when loosening the lug again. After 1-2 hours the locks stick fairly reliable. Nevertheless, this should not be placed within reach of the little ones, because the flaps widen over time and then probably be operated by children. We therefore safeguard the sliding closet doors of our closets and the closures are mounted in our grip width (about 1.5 m) but outside the reach of our children and so far (for 3 months), the cabinet doors stay or the contents in the closet. For closets: A strong buy recommendation.
