addAlock

I purchased addalock because I'm a single female that lives alone in an extremely bad neighborhood and I wanted the extra peace of mind in knowing that my door had the extra lock on it.
And from what I had a male friend of mine very seriously and with all his strength attempt to get into my apartment, using ONLY addalock, not applying my other locks; to test the product out I can honestly say that addalock truly works! No matter what my friend did, he couldn't get in.
Definitely recommend checking out addalock if you've never heard of it before, you'll be impressed. Excellent product not just for your home but also when traveling on your hotel door as well.
