Review on Childproof Door Lever Lock - Prevent Toddlers from Opening Doors Safely with Easy One Hand Operation! Superior ABS Material & Damage-Free 3M Adhesive - Ultimate Child Safety Door Handle Lock, 1 Pack by Michelle Collins

Came in very basic packaging but this is a very good lock that is a must have in any household with young children or even a household with children who want to be ready. Haven't installed all of them yet but tried one over my door and it's just what I was looking for to control the doors at home. My 2 cents below: Pros: - Very easy to install and use - They have a nice build quality - Solid and durable - No drilling required. It has a large 3m double-sided adhesive on the back to stick to the door. Cons: - Not very reasonable price.
