Customer Reviews

Rated 3.7 out of 5 by 12 reviewers.
Rated 2.0 out of 5.0 by Poor quality About 20% of them would not lock. Poor quality allowed the door to be opened with the lock in the locked position. Notches were too rounded to allow positive lock. July 26, 2016
Rated 5.0 out of 5.0 by reasonably priced, good product good alternative to other costly products to secure the door with a toddler running around. April 26, 2016
Rated 5.0 out of 5.0 by inexpensive peace of mind Our front door has a lever handle that unlocks the deadbolt when turned that my toddler can easily open... I've looked at various products to remedy this, but the door design limits my options...I then bought a $21 the lock locker which was an absolute waste...it easily fell off the door...I went to home depot and decided to try this flip lock...I installed it in 5 minutes and am absolutely delighted at the result! My front door is secure and my toddler can no way open the door... what a relief, I tell you! December 27, 2014
Rated 1.0 out of 5.0 by Did not latch out of the package, 2 in a row! Buy something else! I bought 4 of these to baby-proof some non-essential interior doors easily. I pulled one out & the latch could not swing over far enough to actually get into the lock position, it was like the hinge area had been squished or something? Thinking it was a fluke I opened a second & it had the exact same problem!! How can you possibly mess up something this simple!? They will all be going back to HD, I've still got 2 unopened ones in case they give me any grief returning them I can pull another out of a sealed box to show them. I'd recommend going to the store & picking these up in person to make sure they actually work first! July 23, 2011
Rated 5.0 out of 5.0 by secure but not gaudy These unobtrusive locks are perfect for keeping little ones in and bad ones out. Wish they stocked them in the store. February 10, 2015
Rated 4.0 out of 5.0 by Decent quality The lock arrived fast. The lock is a little sloppy compared to the same type I have had in the past. It still works though. September 23, 2014
Rated 5.0 out of 5.0 by great purchase; easy to install I have purchased over 10 of these and used these both for security and toddlers; they work great. I have them placed up high on the pantry door and all external doors to keep the toddler inside. Works like a charm. May 5, 2014
Rated 5.0 out of 5.0 by Great safety feature for homes with toddlers! We live on a busy street and have a 4-year old. This gives me great peace of mind to know that he may be able to open the door like a big boy, but unable to actually get outside without one of us with him. July 16, 2013
