Eco-Baby Sliding Door Lock, 4 Pack Child Proof Safety Window Locks for Glass Doors

These sliding door locks are amazing. These stopped my granddaughter from escaping the house. They are easy to install and very strong.

I installed one of these on my back sliding glass door near the top and told no one. I wanted to check out their strength and adhesive. Well, these little buggers were easy to install, easy to use, and certainly still standing the test of functionality. They are strong and would recommend. Time to test out on windows.

So easy to install. Hardly noticeable & easy to operate. Nice to have added security.Great value.

These are very very easy to install. They are also very extremely durable

Love Love Love how easy to install these are! And even better to keep sliding glass doors and windows locked!!! I would definitely recommend these and would probably buy them again in the future if needed! Great bang for your buck and not cheaply made. Thank you for keeping my household safe!

The price is for a 4 pack, and they stick so well that when I tried removing one, I had to use a knife with some force because it was impossible to remove with my hands alone. They are well built, don't feel cheap, and they work well at keeping slide doors from opening at all with just 1 piece.

Giving 3 stars because they are easy to put on, easy to use and are good quality. I just wish they were so thick. It started to bend metal of the sliding door frame. More than likely my fault for not reading how thick they are but when it says for slider doors I just go with that. Wish we could use them!

Sticks very well, works great on sliding glass door and adds extra security on the front windows and baby/toddler windows in the house. I would definitely buy again!
