Rated 4.4 out of 5 by 18 reviewers.
Rated 5.0 out of 5.0 by Great latch for keeping toddlers from letting themselves out. Simple design, but effective. I like that it will won't damage the trim and door when removed. Just some putty in two holes on the jamb. June 3, 2014
Rated 5.0 out of 5.0 by Outstanding Service from HomeDepot and Great Product from First Watch Security First off, my hat goes off to HomeDepot for offering this product in every color and finish available and for offering this product with FREE Shipping! I had this product sitting in my mailbox four days later and paid less than $2.50. You can't buy anything on Amazon for less than $25 and get free-shipping (at least under most circumstances). Now for the product... It's a simple device and one designed primarily to keep the little rug rats from opening up the door and escaping the house. My primary purpose for using this lock was to secure an interior door on the main level of my house at the top of a staircase leading down into the basement. My basement is accessible from the outdoors and if an intruder were to enter into my house through the basement, he or she could quietly slip upstairs and into the main living area without being heard. Now this little flip lock isn't going to be powerful enough to keep out a willing and able bad guy, but it will create one heck of a racket if someone decides to kick down the door. This in-turn will create just enough noise to wake me out of bed thus allowing me the opportunity to grab my "freedom defender" from the nightstand. Installation is a breeze. It fastens into the door frame leaving only the swinging hinge exposed making for a clean installation. No holes are drilled into the door so if or when you decide to ever remove the flip lock, there won't be any visible holes except for the two inside the frame which can easily be filled and painted. There were two little additional screws which I could not seem to figure out what they were for. Possibly for a non-standard door installation though the instructions included with the product were not clear. March 27, 2012
Rated 4.0 out of 5.0 by works great!! This product is way cheaper than buying those way more expensive baby proofing products. These latches look great and work great. The latch operation does take a little bit to get used to, but well worth a couple bucks. April 3, 2012
Rated 3.0 out of 5.0 by Ok product It works well enough. I don't think it's too sturdy. My husband said if someone were to kick the door, it wouldn't stop them from getting in. But it gives me some peace of mind that my five and three year olds aren't going to be able to unlock the door while I'm in the shower. July 30, 2013
Rated 5.0 out of 5.0 by Works Great! Purchased the flip door lock as a supplement to deadbolt. Installation takes less than five minutes. December 31, 2013
