Okay, so I bought this little alarm on a whim—no specific purpose, just thought it might be useful someday. Spoiler: It’s WAY louder than I expected!

First off, delivery was lightning fast (2 days). The device itself is tiny—about 2.5" x 4"—and needs a 9V battery (not included). Pro tip: Don’t cheap out on the battery. My rechargeable NiMH at 8V failed miserably—it just hummed like a confused robot. Stick to fresh 9V+ batteries!

The setup? Dead simple: Turn it on, wait 10 sec for the red light to go off, and bam—it’s armed. Tilt it slightly (or, in my case, open a drawer too aggressively), and it SCREAMS. Like, brain-pain loud. My phone measured 85dB, but my ears registered it as "why did I do this to myself."

Bonus hack: I soldered extra tilt switches to mine (for my e-scooter) so it triggers if someone touches the lock or basket. Worked like a charm! Just don’t use weak batteries—learn from my fail.

For $5? Absolute steal. Just... maybe warn your neighbors first.
