Let me start by saying this little gadget has been a lifesaver for my peace of mind. The Tiiyee Door Handle Alarm delivers exactly what it promises - instant, ear-piercing alerts when someone touches your door. At 120dB, it's louder than most smoke detectors!

The setup couldn't be simpler: pop in 3 AAA batteries (not included), hang it on any door handle, and you're protected. I've used it both at home and during hotel stays, and that sudden alarm blast definitely startles would-be intruders (and occasionally me when I forget to disarm it!).

What really impressed me were the customizable features. You can choose between alarm or chime modes, plus adjust sensitivity from hair-trigger (great for toddler safety) to only triggering when the knob turns (better for high-traffic areas). The flashing red light during arming gives clear visual confirmation.

Now for the real talk - there are some quirks. Like other reviewers mentioned, there's no silent way to turn it off once armed (expect a brief alarm when disarming). Also, cheaper batteries make weird noises as they die. But considering the price point and effectiveness, these are minor tradeoffs.

Pro tip: I keep one on my teenager's bedroom door and another on our patio - the vibration detection works even through glass doors! Whether you're protecting curious kids, elderly family members, or just want extra security while traveling, this affordable alarm delivers serious bang for your buck.
