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

Installed these on three critical doors and now we have peace of mind until she figures out the system. Our granddaughter is a handful. They work as advertised, just dont know what the door will look like after removing them.

These look bulky around the door knob, but they do work well against my 80 pound dogs trying to open bedroom doors.

Small tool yet it creates a sense of security for my apartment and also keeps my toddler from walking out the door when she decides she’s ready to go! Great buy

Very easy to use and adhesive is strong

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

Keeps our toddler from helping himself to more puffs, graham crackers, and goldfish throughout the day. Easy to install, easy to use. Although, all of the grandparents struggled to figure out how to use it, which made us laugh (they are fine now, once we showed them. They all claim it’s because they “didn’t have contraptions like this back in their day.”) Great buy overall, don’t hesitate!!

Easy to use and install! I followed the advice of one of the other reviews and installed it upside down since my lever allows me to open the door by lifting it up. By installing it upside down, I’m able to get away with not having to lock the device since my child isn’t tall enough yet to lift the lever up. When my child does get tell enough, it’s so easy to use and unlock. I don’t know how it’ll be when it’s time to remove the lever…but it doesn’t bother me because I don’t like the color of my door anyways. It’ll need a new coat of paint by that time. I highly recommend this product.

Sticks on with a 3M adhesive strip, so takes about 2 seconds to install. Toggling it between locked and unlocked is simple and with it requiring a button press both ways, you can prevent being locked out by little ones playing with it. Works exactly as advertised

I teach an autism class and I have a student that is a runner. We got these locks last school year and the student was not able to open the door! I wanted to make sure that I had extras in case the stickiness became lax. The student still isn’t able to open the locks so job well done!

Great product
