Improved Childproof Door Lever Lock (2 Pack) Prevents Toddlers From Opening Doors. Easy One Hand Operation for Adults. Durable ABS with 3M Adhesive Backing. Simple Install, No Tools Needed (White, 2)

Great Product and easy to use.

I you should really get some of them love them

This would work well for a lot of lever handles but did not work for our front door as the handle sticks out further than the locking device. Other than that they would be easy to install and easy to use

Great idea, but my toddler figured out how to open the door within a week of installing this on our back door. So, didnt work for us. :(

Easy to install and use

bought this as a solution as we live in an apartment, my child sleeps in their own room and my husband works a night shift so we can’t deadbolt the door, has worked great and i can finally sleep not worrying about my child breaking free in the middle of the night

Needed that to prevent our retriever from opening the doors, worked like a charm.

Door cannot be opened from the outside once locked from the inside so it gets the job done.

Works great. Super easy to install

My door knob handle must be closer to the door than other levers because there was no way I could apply this mechanism without turning it at a 45⁰ angle, otherwise the knob could not be pulled down to open the door. I didnt realize that the first time I applied it and had to rip it off the wall which pulled paint off (oops! Shouldve used floss or fishing wire instead to gently scrap the mechanism off). That said, it works! It doesnt look pretty since I have to keep it at an angle, but it does the job well and sticks to the door very well.
