Okay, so I've had these chain locks for about a month now, and here's the real tea ☕

First off - installation was STUPID easy. Like, 'I-did-it-while-drinking-coffee' easy. The screws are included (bless) and they work on my weird apartment windows that nothing else fits.

The security factor is no joke. My paranoid self actually tried yanking the door open (for science!) and these bad boys held strong. That stainless steel chain? Thicker than my last relationship.

What I really love is being able to crack my windows for fresh air without turning my place into an open invitation for burglars (or my dumb cat who thinks he's an outdoor adventurer). That 4-inch gap is perfect.

Only minor gripe? The silver finish shows fingerprints like crazy. But honestly, that's me being extra - they could be neon pink and I'd still use them for this peace of mind.

10/10 would recommend to anyone who wants to feel safer without turning their home into Fort Knox. Plus that lifetime warranty gives me warm fuzzy feelings.
