Prime-Line U 9888 Flip Action Door Lock – Reversible White Privacy Lock with Anti-Lock Out Screw for Child Safe Mode, 2-3/4” (Single Pack)

So I went the rounds on other products before I settled on this simple solution that ultimately was the only one that met our need. The goal was to keep our 3 year old in our house. We were able to use doorknob covers for 2 of our external doors, but our patio door has a handle-type opener and couldn't accommodate a knob cover. The door also couldn't be converted to a knob due to the custom opener / deadbolt system that was installed. Our problem was that the door is slightly offset from the wall and other products proved to be too bulky to allow the door to function after installation. I briefly gave up on finding a solution, but my son later escaped and had to be chased by my wife for several blocks before she was able to catch him. (The boy gives new meaning to the term "stinker") I went back to the drawing board and found this product. I was pretty skeptical, as all of the other products that I had tried were far more complex and much more expensive. I was very pleased to find that the product worked great and installation was a 2 minute process. Now my son is safely contained to terrorize my wife in the comfort of our home and we no longer have to worry about him carrying committing acts of terrorism to the neighborhood at large. It has been several months and he hasn't gotten out yet. (well in all honesty, he did get out once, but that involved a perfect storm of chairs and broom handles and luck, and tiny devious ninja skills. We confiscated the ninja tools (broom handle) and he was back to being foiled. House, thy name is Alcatraz. Thank you for making a product that is as simple as it is effective.

Easy to install and works perfectly.

These are so simple and minimalistic which I love because they don't attract the attention of little eyes (who seem to take visible barriers to mischief as a personal challenge). When locked, the door doesn't even budge, which, to a toddler just means "hmm I guess this isn't a door after all..." where as a door that can be jiggled or slightly opened before hitting resistance seems to inspire more tenacity of "ooo this door wants to open but it's stuck.... I better slam it as hard as I can repeatedly" The only downside is this can only be operated from one side of the door and only on doors that open out. the fact that it works so perfectly and it's less than $3 more than makes up for those things though, so all is forgiven. for doors this lock won't work with, I love the "top of door locks" that slides on top of the door itself. I know aesthetics take a backseat when it comes to child safety, but these are so clean and nice looking, they would win a baby-proofing beauty contest in addition to whatever accolades they would be awarded for their functionality, sturdiness, ease of install/use, and price!!! Anyone who has never tried to thwart the brilliance of toddler mischief will think I'm crazy for writing such a long, glowing review of a $3 door lock, but other parents, I know yall feel me on this... -_-

Does what it advertises, but be aware the swinging part of the hinge that locks is not very deep. So if the gap between door frame and door is very large, the lock won't catch. Quality is good, though.

We got it to keep a child from escaping the house. It took about an hour to install because the screws are made of soft metal and immediately got stripped so the screwdriver could no longer grip them. After scouring the house for spare screws or approximately the same size we got it secured to the door. Finally, after the frustration of dealing with it for so much longer than should have been necessary, we turned the latch so it fell into the notch and tested opening the door. It opened right up! The notch is so shallow and rounded that the gentlest pressure against it from the door lifts the latch right out and it opens with virtually no resistance. What a piece of junk this is! Angry at ourselves for trying to save a few dollars when the security and safety of a child were on the line, we immediately ordered a higher quality door lock. Sure, it was about $10 more, but it installed within 5 minutes and most importantly, it prevents the door from opening! The peace of mind of knowing no young children will be escaping or opening the door for strangers is worth the extra cost. Avoid this cheap piece of junk! It's going in the garbage where it belongs.

Works as it should. Right price too!

Works as it should to keep our toddler from opening the front door and bolting. It blends in with our door so it's not ugly and noticable

I've been using one of these locks for many years, to child-lock a closet door, and it always works well. So I bought another one, and it barely works at all. The latch doesn't easily drop into place to lock, I can pull the door when it is in "lock" position and the latch will open. The pieces aren't well aligned, and globs of paint make it even more difficult for the latch to fall into place.

Good product. Simple use simple install. Particularily good if your door is inset in a particularily deep door frame like mine and you dont have much clearance for other unit. Used this as a door lock to keep my father with alzheimers from wondering outside. Its simple to use but will confound someone with dementia.

Great quality and keeps our toddler from unlocking the front door!

Easy to install and inexpensive. It is designed for ensuring privacy rather than security. I used it to lock a basement door connected to a rental legal suite. When it is removed, it only leaves two holes on the jamb, not on the door, and won't make the door looks ugly. The two included screws are quite small.

Using it for babyproofing the house. Easy to install, small and discrete. Much more convenient than those big clunky handle guards. However, you do need to jiggle it a bit to flip it open. The mechanism is not very smoothe. Note: you can only use this on doors that swing towards you (ie. hallway closets, door to basement etc)

Have ordered and installed many of these in the past, and they worked great. This order of 2 units do not function properly. With little door pressure the latch opens easily whereby it should not. I would not recommend buying these defective items as they do not work.
