Let me start by saying this: the HoneTeek Door Alarm Sensor is LOUD. Like, 'wake-the-neighbors-and-scare-the-dog' loud. I tested it on my back door, and the 108 dB siren made me jump out of my skin—definitely not something you'd want for elderly care (as one reviewer painfully discovered).

The remote control is a game-changer though. Being able to arm/disarm from bed or the couch is incredibly convenient. I used it when coming home late with groceries—no fumbling with tiny buttons in the dark.

Installation was stupid easy. The adhesive held strong on my wooden door frame for weeks... until it didn't. Like several reviewers, I experienced the dreaded adhesive failure after about a month. Pro tip: use your own heavy-duty tape.

The sensor technology works exactly as advertised—any separation beyond 1cm triggers that ear-splitting alarm. I tested it repeatedly on windows and doors, and it never failed to detect openings.

Battery life seems decent (still on the included AAA batteries after 6 weeks), but be warned: when those batteries die, the unit becomes a paperweight. No low battery warning despite claims.

For $20? It's a decent security band-aid. Just don't expect premium quality or longevity. Perfect for renters or temporary situations where drilling isn't an option.
