What Our Customers Are Saying


This works perfectly... I feel much safer and secure. It's super easy to use and I didn't have to install anything on my door like screws. We now have one on our garage door too. Very convenient and highly recommended

We had a run of breakins in our area and so we bought this device hoping to stay safe. Our Ring device recorded someone at our door during the night and we think this may have prevented a burglary. So THANK YOU for this product!

George and Sue


After searching for a way to secure our door, we found lok and blok. We didn't want to have anything screwed to our door or some ugly thing permanatley attached. This was a no brainer and we use it everyday. We bought our parents some too!
