This is the perfect child safety lock I have been looking for my sliding door to my patio. I have tried others, which did not work. It was very easy to install this product and very easy to operate. Kudos to the designer. The quality of the product is also very good. Moreover it does not damage the door.

We have low windows in our home and our kids used to try to crawl out of them. These work really well.

Really well done. Strong, simple and effective. Very happy with my purchase.

My two year old has recently started opening doors, and figured out the locks. She loves to be outside which is great but to keep her safe, we got these for the patio doors. It works perfectly, my daughter is very strong and big for her age. She can pull on the door as much as she wants, it never moves. Definitely recommend it!

Installed on a sliding door wardrobe at the top of the door, out of the reach of children, very easy to install and use. Super practical and sturdy
