Bests & Worsts Reviews from Amazon

I bought this as a theft deterrent. Well after looking at it and reading online, I discovered it can be opened WITHOUT tools in less than 5 seconds. That's anti theft? I modified mine for mounting before realizing this, so no returns. I wasn't going to tell without having a solution, maybe Sentry will change the design. Take your fist and hit the front door strongly above the knob at a 45 degree angle downward, at the same time turning the knob. Open in less time than to enter to code. Pityfull! I fixed it by glueing a 3/4 inch round magnet on the lock bar just above the electric solenoid, half off over the bar to the solenoid. You may have to try different magnets to get the right strength, but the first one I tried worked, so maybe not so critical. The magnet keeps the solenoid bar from falling so easily. But, a large hammer may still be a problem, didn't try. Sentry, modify the design.
