Okay, so I got this little security gadget hoping it'd give me peace of mind during my solo travels. Here's the real tea:

First off - that 120db claim? It's LOUD when it works properly. Like, jump-out-of-your-skin loud if you accidentally trigger it at 3AM (ask me how I know). But the volume seems inconsistent - sometimes ear-piercing, other times barely noticeable over hotel AC noise.

The motion sensor is... finicky. You really have to disturb it directly for the alarm to trigger. My backpack got jostled in a crowded train and nada, but brush against it while unpacking? SCREAMING ALARM TIME.

Build quality feels cheap (it's basically plastic with questionable English instructions), but hey - it did scare off someone trying my hotel door handle at 2am last week. For that moment alone, I'm keeping it.

Pro tip: Bring extra batteries and prepare for trial-and-error installation. Would I buy again? Maybe as a budget option, but don't expect James Bond-level security here.
