Tools and Hardware Reviews of Techko S184 Portable Door Knob Guard with Vibration Sensor
Customer Review: effective
Summary: 4 Stars
works well for our condo...the only thing would be nice is a way to shut off the unit without setting it off...like a remote. it is nice and loud for a little unit.Customer Review: great
Summary: 4 Stars
Although the chime is VERY loud, and sometimes seems to be a little too sensitive, we have been very happy with it.Customer Review: SECURITY DOOR KNOB GUARD
Summary: 3 Stars
It is made with cheap plastic, however, the sound is very loud and effective. For something that just hangs on my door knob and is used as a deterant or just to give me plenty of time to get my weapon, I am glad I purchased it.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.
Customer Review: Can't disarm without LOUD EAR-PERCING CHILD AWAKENING noise
Summary: 2 Stars
It works, but it is sensitive. Half the time you can't turn it off without waking up the neighborhood. I tried to cautiously hold down the unit when turning it off. It is possible to quietly disarm, but it is hard. Imagine one of those movies where the guy is trying to disarm a bomb without blowing himself up and everyone around him. THAT is the kind of sensitivity it takes to turn the thing off. Purchase only if you have patience, don't have kids, and you are halfway deaf.
