Essential Info

The Techko S184S Ultra Slim Door Guard Alarm is a simple and effective solution that can provide protection of your valuables. A typical installation will have you hang the device on your doorknob, however it can be hung from most any other item as well. The instant your door is opened or a vibration is detected, a loud alarm will sound for 60 seconds and an LED will flash, instantly letting you know of the disturbance. For basic alert notification, the Ultra Slim Door Guard Alarm can also be set to chime mode which will sound 3 times when a vibration occurs. This product is powered by three AAA batteries (included).

    I love the idea of the Slim door Guard alarm but in practical terms its too fragile hence the 3 stars. Needs to be stronger built as otherwise I can see myself having to replace too soon.
    WILLIAM -- alexandria, VA   4/5/2012
    works well
    LARRY -- asheville, NC   10/27/2011

    LINDA -- verona, KY   9/1/2011
    Way too loud for hanging on my daughter's dorm door where someone might accidently hit the handle. should have a volume adjust or a choice of chimes/bells
    CAROL -- macon, GA   7/8/2011
    This was our second one... the first worked great for years, but this one alarmed with no door movement in the first month of use.
    ALAN E. -- antioch, TN   6/24/2011
    Cheaply made but fully functional.
    PHYLLIS W -- davenport, FL   11/23/2010
    I am very pleased with this product. It works well and makes me feel safer. My sister has the same product name, but it is a barking dog alarm and it works great too. That was actually the one I was searching for but when I could not find it, I found this and ordered it and it works equally well.
    ELIZABETH -- waterford, MI   8/21/2010
    Works very well, easy to use and set up. Sound level is high enough to deter entry and alert the user.
