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

This works well and installs easily, but be careful when using on interior doors. Exterior doors, the inside and outside handle generally operate independently, but on interior doors the inside handle and outside handles move in tandem. I installed this and set it in the locked position with the door open. My little one wasnt home so I didnt close the door. Later, I went to use the restroom that this lock was protecting, and even though no one was home I closed the door behind me out of habit. When I went to exit, I couldnt, and the outside handle was blocked by this device and the inside handle cant turn if the outside handle cant turn. After mulling over my options and deciding to go hulk mode on the handle, it dawned on me that my bathroom has french doors. :) So luckily in my case I just released the lock on the second floor and pulled the doors open. But if it were a single door, hulk smash indeed. My only wish for this item were if there were a second model for exterior doors that had a spring loaded auto lock option, in which the device would always return to the locked position. Reason being, we have a heavy traffic home, and people are constantly coming and going. When people leave, its easy to forget to open the door, set the lock, then exit, so the child lock stays engaged after you leave, meaning the door is often times left unlocked when people exiting forget to do this. So we have gotten into the habit of checking it throughout the day. If it had some sort of spring loaded with soft auto lock, people could exit and it could return to a locked position automatically. Obviously this would only work for exterior doors or doors in which the inside and outside handles can be operated independently and dont move in tandem.

I was concerned but now I’m confident these were a great buy

Product was easy to install and use. Works great.

My kids are 3 1/2 and 2 years old. They’ve yet to figure these out. They’re easy to use and to install

This item did not stick how it was intended. Do not buy.

My puppy learned how to open doors very early on. These locks are amazing and she can’t open doors anymore. My puppy is safe and I can breathe a sigh of relief that she won’t be getting into anything potentially dangerous.

Great adhesion, super easy to install and easy to use!!! We were having to lock every single door in our house to keep our 2 year old out of bedrooms. It was a hassle to find things to turn the lock back open. These are super convenient and doesn’t look tacky on doors.

My husband has dementia. I use this to keep him from getting in his closet because he forgets to go to the bathroom and sometimes pees in his closet.

Very easy to install and does the job. These go on quickly and keep kids from opening doors they shouldnt be able to open.

This was used at the grandparents house while visiting for a week. Adhesion: I misplaced it initially and was able to quickly pull it up again (no paint came off the door) and re-stuck it. In those first few minute after sticking it was easy to remove, but without a few hours/a day it was fast stuck. I used these to keep my older child from opening the bathroom door (I kept it on the outside of the bathroom door), to stop children from getting inside (infants/toddlers are top heavy and can drown in toilet bowl - true story). I also kept one upstairs in the room my family and I were staying in so that when I put the kids down to sleep I could lock it from the outside knowing no one could fall down the stairs if they opened the door. Children can’t lock it from the outside... but... one morning as I was cleaning the room and my husband took the kids down he automatically locked the lock and I was stuck. Big house, so no one could hear my knocking. Thankfully I remembered I could use my phone and I was rescued, but that was a little stressful. So if you have older kids who can accidentally lock you in then this might not be the right fit. Otherwise no complaints and it did its job perfectly.
