Let me start by saying, this little device has been a game-changer for my home security. The Rerishom Door Reinforcement Lock isn't just another piece of hardware - it's peace of mind packaged in sturdy aluminum alloy.

The installation was a breeze - took me all of 5 minutes with my trusty drill. What surprised me most was how substantial it feels once mounted. The mechanism has this satisfying 'click' when locking that just screams reliability. I've tested it numerous times (maybe too many, according to my annoyed partner), and that 800 lbs force resistance claim seems legit.

Living in an area where break-ins aren't uncommon, I appreciate how this adds an extra layer of protection beyond standard deadbolts. The dual-groove unlocking system is genius - simple enough to operate quickly in emergencies yet secure enough to deter forced entry. I particularly love that it serves as both security against intruders and child-proofing for curious little hands.

Now, let's talk about the elephant in the room - those infamous screws. While mine held up fine during installation, I've heard enough horror stories about them snapping to suggest having some heavy-duty alternatives on hand just in case. It's literally the only downside in an otherwise flawless product.

Pro tip from personal experience: Install it high enough that pets can't accidentally lock you out (ask me how I learned this lesson). Also works wonders on garden doors and double doors, though you might need some minor woodwork for perfect alignment.

A year into using these locks on all my exterior doors, they still function like new. That smooth operation combined with the solid construction makes this one of those rare purchases where you immediately think 'Why didn't I get this sooner?' If home security is a concern (and let's face it, when isn't it?), these should be at the top of your list.
