### ⭐⭐⭐⭐⭐ Review
*by P***L on 8 January 2019*

Originally I had watched a Facebook video my girlfriend had sent me about this new security product and i thought this has got to have a catch or be phony.... So what could $22 bucks hurt spending it to try this out so i bought it and the only thing i didnt not like is i got uline instead of prime-line not a big deal theyre all the same. I installed it shortly after recieveing it with my impact driver with the 3"inch screws supplied and then i got my girlfriend to lock it so that i could test its strength, i am 200+lbs 5"8 heavy frame 56% muscle fairly good shape and my cousin who is 5"10 about 200 we both hip checked as well as tried 10+ times to boot the door in with just that no lockes engaged and shoulder check it... Result im pretty sure that even if u have a good new solid house your hinges would give out before this thing will -Great buy -Good value -Super Strong ( no to brag but ive ripped exterior doors on a new house off by accident and this held up to me) -800LBS to bust it -Quality product -Easy installation(you will need an impact driver for this) All in all a great purchase & have reccomended this to my friends and family.
