Improved Childproof Door Lever Lock (4 Pack) Prevents Toddlers From Opening Doors. Easy One Hand Operation for Adults. Durable ABS with 3M Adhesive Backing. Simple Install, No Tools Needed (White, 4)

So this item would be good if you are trying to keep a toddler from opening a lever door knob... I was buying it to keep my huge dog from opening the front and back doors. It was easy to install, pretty sturdy when I tried it myself. My dog went to jump up and use his paw to open the back door and it fell right off. Adhesion could be a little stickier, but I understand my use will probably not be the average persons use.. lol Overall a good product

Toddler at 2 can’t open and consider them a mystery. He pulls on them and finally gives up.

It works for my 2 year old but my 4 year old can open it pretty easily. 2 stars because it does at least slow down my toddler

Works great but they will take the paint off of your door

Keeps my little kiddo from opening the door to strangers and running out into the street

Easy to install, easy to use, and protect your little one.

My son learned how to unlock and open doors early so these were a must. They work really well and he has not been able to undo it at all.

My 3.5 year old likes to open our front door occasionally which scares me so I got these to make sure she can’t do it when I’m not looking. Works great and would definitely recommend!

Love these door locks!

This product is good. But might not be able to open from the other side. Also, the handle area had better be a flat surface
