First off, this little gadget is LOUD. Like, 'make-your-neighbors-jump' loud. I tested it inside my car, and the 108dB alarm is no joke—it’s piercing enough to scare off anyone messing with your ride. The dual red light flashing adds that extra 'back off' vibe, which I love.

The magnetic mount is genius. No screws, no sticky residue—just slap it on any metal surface in your car (or truck, or even your bike). I moved it from my door panel to the dashboard in seconds when I wanted a more visible deterrent. Super convenient for folks who hate permanent installations.

Sensitivity is a double-edged sword. It caught every little bump (even a strong gust of wind once), which is great for security but means you might need to tweak the settings if you park near busy streets. The remote’s 66ft range worked fine for me in parking lots, though don’t expect to disarm it from your apartment window.

Bonus: It’s not just for cars! I stuck it on my shed door during a trip, and the alarm went off when a raccoon tried its luck. Battery life? Solid—two AAA batteries lasted me two months with daily use.

Wishlist: A blinking light even when armed (for that 'always watching' effect) and maybe an app alert when triggered. But for under $30? This thing’s a steal—pun intended.
