Tools and Hardware Reviews of Techko S184 Portable Door Knob Guard with Vibration Sensor
Customer Review: Nice when it works, but erratic
Summary: 2 Stars
This is a basic door knob alarm. The idea is that you hang it over the inside of a door and when the door opens, the vibration sensor will set off the alarm. The alarm has two settings - an incredibly loud wail to scare away intruders and wake sleeping residents and a quieter but still reasonably loud chime to announce that the door has been opened. (The second alarm is about as loud as a loud doorbell).
We got this for our toddler's room, in order to alert us when she got out of bed. After a few weeks, we took it off. When it worked, it was fine, but about 50% of the time, she opened the door gently enough that the alarm didn't go off. If it was a little more sensitive, it would have been great for us, and it would probably be fine for a "sticky" door that can't be opened smoothly, like a weatherstripped exterior door.
