1.0 out of 5 stars False Security - A Pointless Exercise
Reviewed in the United States on 9 June 2020
The screws provided are so soft they fail DURING INSTALLATION! Look at the picture! That is what happens when you try to screw this into a 2 x 4 stud - - complete failure. The screws are far too soft to withstand the torque needed to get them into your studs.

In fact, the entire device is made of this same ultra soft, ultra cheap steel. This product is "eyewash" or "eye candy" for those who want security, but have no expertise. It is so cheaply made it is not worth the time and bother to install it. Yes, they fooled me. But ONLY ONCE!

I bought two, and they are being returned immediately as rubbish!
