Happy Face –
Fabulous. Easy to install. Bombproof.
Okay, there is a very short, very rude person in my house who wanders into wherever they want with no regard for anyone’s privacy. (Yes the person is two.)So we installed these on the bedroom doors in our home and it has completely solved the rude person problem.They’re not like the hotel room ones that usually allow you to open the door a couple inches. The door does NOT open when this lock is properly installed and deployed.I’m even thinking about putting some on the door leading down to the basement so that no person and no THING in the basement can open the door into the hallway and come eat us all in our sleep.Conveniently, this comes in a four pack, so I don’t even need to purchase a new one for that!If you have two bedrooms and a front door and a back door you could have them on all of those, which would be great!Of course they’re “privacy” locks, but they would do fantastic backing up your regular door locks. Only operable from the inside, of course.I suggest installing them at a different height than your light switches, by the way. A little higher or a little lower. And not at “handle” height, of course.These only work from the “swings in” side of a door, by the way. You COULD install one on the other side, but people would think you’re strange.Great purchase. Solid. No ragrets.

Locks for the family
Amazing locks, have had them for two almost three years, absolutely love how simple it is to use but keeps the kids and adults out. Easy to install and easily able to open quickly or close but has lasted a long time well being very functional.
Clayton Miller –
Highly recommend.
These are awesome door locks, they feel very secure. We initially bought these as child safety locks because our kid figured out how to work regular child safety locks and started going out the front door. Very easy to install, and stylish. very functional and secure.

Great safety product
Works as it should! Easy to install. The door doesnât move at all when latched. Nice long screws to go all the way to the stud for security.

Reliable Home Security Door Reinforcement – 4/5 Rating
I recently purchased the GreaTalent 3PACK Home Security Door Reinforcement Lock and found it to be a reliable addition to my home security measures. I would rate it 4 out of 5 stars.This door reinforcement lock offers an extra layer of security, providing peace of mind for homeowners. It effectively strengthens the door, making it more resistant to forced entry attempts. The solid construction and sturdy materials used in the lock inspire confidence in its durability and effectiveness.Installation was straightforward, and the lock was easy to set up. It fits well on most standard doors, and the package includes three locks, which is convenient for securing multiple entry points in the house. The locks are childproof, adding an extra layer of safety to protect children from wandering outside or unauthorized individuals from entering.While the GreaTalent door reinforcement lock delivers on its security promise, there are a few areas where it could be improved. The design could benefit from additional aesthetic considerations to blend seamlessly with various door styles. While this doesn’t affect the lock’s functionality, it would enhance its overall appeal.In conclusion, the GreaTalent 3PACK Home Security Door Reinforcement Lock is a reliable and effective solution for enhancing home security. It provides an extra layer of protection, is easy to install, and offers childproof features. With some minor design enhancements, it would be an even more impressive product. I highly recommend this door reinforcement lock for anyone seeking to bolster their home security measures.Sincerely,Mark
