Okay, so I got these sliding window locks hoping they'd be a game-changer for child safety and security. Here's the real deal:
First off, the build quality is solid – that zinc alloy feels sturdy and definitely not something that'll bend or break easily. The key separation design is a nice touch for peace of mind with kids around.
But here's where things get tricky... Installation was way more complicated than expected. The clamping distance is super specific (like 3-6mm precise), and if your window frame isn't exactly right, forget about it. Mine wouldn't lock properly on either the sill or frame.
The concept is brilliant – I love the idea of being able to crack windows for ventilation while keeping them secure. But unless your windows match these specs perfectly, you might end up frustrated like me.
Would I recommend? Maybe... but only if you're 100% sure about your window measurements. Otherwise, prepare for some installation headaches!
