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

I purchased these to keep my cat from opening closed doors. They are easy to install and use!

We use them for our whole house. The very first one we installed 6 years ago and it’s still holding tight with no signs of wear and tear. We just had to get more for the rest of the house

Super useful - despite being non-human apparently my cats taught themselves how to open doors and I got tired of coming home to everything being open and mildly ransacked. Theyre easy to work and can be opened with one hand while Im completing my morning routine. I am in an apartment so being able to take them off will be important once I leave, but well see. NOTE: a friend locked themselves in the bathroom by accidentally putting the bottom lever back up before going in and closing the door. Unless you know that your doorknob doesnt move upon opening/closing make sure to keep the lever down!!

Super easy to use and does the job!

Easy enough to install, and have been holding up for over a year now.

Nice but didn’t work for our straighter door handles. We have a very smart cat that has figured out how to pull the handles down and she lets herself into any room she pleases.

It stands up to our dog - she can’t open the doors.

good

Works great!

My little 2 yo kept coming out of her room and terrorizing her big brother every morning. We decided to get one of these to at least keep her a bit contained and allow our son to get enough rest (so he doesnt get crabby). Its very easy to install, and it is very effective. My little 2yo is STRONG and has not broken this off by pulling on the doorhandle (been about 3 months now). The only thing I would be worried about is accidentally locking myself in the room. I havent done it yet, thank goodness, but Im sure Id feel stupid af if I do.
