    All you had to do was look it says on the page it does. Cheap enough without anyway

  "Using the latest magnetic energy technology, when separate magnet from host, it will immediately send wireless radio, host receives the waves and instant alarm"
  .
  "Super environmental suitability and stability"

    Presumably it makes a loud noise when an intruder opens your door, which would hopefully scare them off.

  How reliable is Tmart.com when comparing with dx.com?

  • 

    jv on 26/06/2013 - 23:15

    what do you mean by reliable ???

    they are both slow, usually 2-3 weeks…

      In that case, I better stick with DX.

      Found a better window alarm from DX for a dollar more. It's up to 105 dB loud and operate with 2 x AAA and 3 x AG13 cells (included).

  The card reader is horrible. I bought 5 last time, all 5 broke within a month. So very bad, even for 50c.
