Let me start by saying these little locks are a GAME-CHANGER. I installed them on both my front door and my toddler's bedroom door, and the peace of mind is priceless.

The 800lbs force claim isn't just marketing - these things are BEEFY. My 3-year-old has thrown full tantrums against the door, and it doesn't budge an inch. The aluminum construction feels premium, not like those flimsy plastic childproof locks.

Installation was stupid easy - took me literally 4 minutes per door with just a screwdriver. The included instructions were clear, though honestly you barely need them. Pro tip: Make sure your door frame is solid before installing for maximum security.

What surprised me most was how sleek they look. The silver finish blends perfectly with my modern door hardware - no ugly plastic contraptions ruining my home's aesthetic.

The only minor downside? If your door isn't perfectly aligned, you might need to adjust the strike plate position slightly. But that's more about your door than the product itself.

As someone who's tried multiple childproofing solutions (and watched my Houdini toddler defeat them all), these are by far the most effective. They've survived daily toddler assaults for 3 months now with zero signs of wear.

Final verdict: Whether you're childproofing or just want extra security, these deliver way beyond their price point. I've already bought two more sets for our vacation home!
