Okay, so I grabbed these magnetic alarms hoping for some extra security without breaking the bank. Here's the real tea ☕

First off - THEY ARE LOUD. Like, 'wake-the-dead' loud at 95dB. When my cat triggered one at 3AM, I nearly had a heart attack (but hey, that means it works?).

The installation is stupid easy - peel & stick with included adhesive. Though pro tip: clean your surfaces first! Mine fell off my bedroom window after 2 days until I properly wiped the frame.

Weird thing - some units have different alarm tones? Like one sounds like a dying robot even with fresh batteries. Not exactly uniform but... distinctive?

For $2 per alarm, you can't expect premium quality. The magnets don't always align perfectly, causing occasional false alarms when my AC kicks on. But when they work? That piercing siren would scare off any burglar (and probably your neighbors too).

Final verdict: Great for temporary security or rentals where you can't install permanent systems. Just maybe warn your housemates first!
