Just installed these sliding window locks and overall, I'm pretty impressed! Here's my breakdown:

✅ Pros: Super easy to install (took me 2 mins per window), comes with 4 locks + keys, and feels sturdy. The aluminum alloy construction gives peace of mind about durability. Love that it lets me keep windows slightly open for air while being secure.

⚠️ Watch out: As some reviews mentioned, CHECK YOUR WINDOW TRACK first! My neighbor couldn't use them because their window frame blocked the key turning mechanism. The product images show ideal window types - measure carefully!

🔑 Key situation: Works great if you don't lose the keys (only comes with 2 hex + 2 vertical keys for 4 locks). Maybe attach keys to a keyring immediately?

💰 Value: For the price of 4 locks, this is a steal compared to hardware store prices. Already recommended to three friends!

⭐ Final verdict: 4.5/5 - Would be perfect if it included more keys and had clearer compatibility warnings. But if your windows fit? Absolutely get these!
