CUSTOMER REVIEWS

Rated 4.9 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by WHY DIDN'T I DISCOVER THIS SOONER?! Sad to say I live at a property full of scoundrels and low-life thieves. So, someone told me about this lock. How great is this invention? A chain lock that can be activated from OUTSIDE of the door. Now, whenever I leave my home, I can be sure that no one is entering my home WITHOUT MY PERMISSION! I will NOT be giving a key to my landlord because that would defeat the purpose, they shouldn't be trying to enter my apartment without my knowledge so, if they say something that will let me know that I have to sue and it also gives people a false sense that someone is home when they really are not. Yessssss! I can't say enough about this product. As for installation, I will say as a single woman, I am NOT handy with a hand drill but, I had to familiarize myself with it. Even though this is a $10 product, the cost of the drill and the bits were almost $30 so, not too happy about that but, still worth it. I'll just have to get more handy around the house. But, overall this is a great buy if you just want people to stay out of places they don't belong :) September 14, 2012
Rated 5.0 out of 5.0 by Very strong, works well Was easy to install, 6 screws that came with packaging. For security minded person this is great to lock your door and only you can gain access with the key to unlock the lock. March 10, 2015
Rated 5.0 out of 5.0 by Great Great product nice design good handling and colour January 6, 2015
Rated 5.0 out of 5.0 by got kids! keep em out! I use this to lock the pantry to keep the kids out of the snacks and taking everything out of the pantry. works great for that. August 6, 2011
Rated 5.0 out of 5.0 by Love it, if you have children that may slide the lock and get locked in this is great! It is as easy as any chain lock to add to door. You can unlock with key which is really great if you have children that may be old enough to slide it but not want to open door for you - this way you can still get into room with the key. It really makes the old chains not as good, since I can also lock it when I leave and my cat can stay in my room but exit (because I use chain not door lock so the crack is there for her) to use cat litter or eat/drink any time. This means my computer is not out for kids so IF you use the child safe on the ones the children use but not on your computer or tv, this is great mostly because of cat. Also if air cond. is not central you would not come home to hot room. September 16, 2014
Rated 4.0 out of 5.0 by Love the lock One of my reservations about getting this type of lock was getting locked out of my own home. The key lock feature is great for someone who would like to be able to still get through the front door without having to break down the door. May 12, 2014
Rated 5.0 out of 5.0 by The Best Device Every Invented Many years ago, I had this product and some how misplaced it. Now that I am a senior leaving in a not so secure complex, I made another purchase. It was the best decision ever made. Now I feel secure knowing that no one can walk-in on me...at home or not. Please do not hesitate and give yourself a peace of mine (easy to sign for packages without opening the door; if some is out of peep hole range you still have some security). Believe me, you cannot put a price on feeling save in your own 4 walls. July 17, 2013
