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

very sticky back, but if will pull apart leaving the sticky back on the door. I used a screw to stick them to the doors to keep them from pulling apart.

I wasn’t sure what to expect with this product, but I am pleasantly surprised it works so well. It’s easy to adhere to the door and simple to use. I’ve had other childproof locks in the past that are difficult to use. This one is great and I’ll buy more for the other doors in the house.

It prevents the door to open and so far it is staying adhered. It serves the purpose. Happy with the product

Keeps toddlers AND smart dogs out. Very sturdy, reliable.

Before our grandkids recently became mobile, we had issues with one of our cats! He is very long, and can stretch enough to reach all doorknobs in our house, which happen to be French-handles! I have purchased multiple pkgs of these to put on every door and have been successful for months keeping him out of closets and bedrooms!! I installed them upside-down so the grandkids won’t be able to flip the bar up once they figure it out!!

Love this product as it helps keep our cats/dog from opening the doors! It’s sturdy and definitely works how it should!

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

I have a Maine Coon cat named Flynn that likes to open doors. I bought these and now he cant open the doors. He does other things too. Ive had to buy child safety locks for the stove and garbage disposer. Flynn is a clever cat. I keep buying things from Amazon to stop him from doing things that he shouldnt do.

These work very well. Easy to use and install!
