    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day


    around 433MHz
    - good range
    - PLL receivers
    The receiver responds very qick
    I like two LEDs on the transmitter
    I also like the alarm sound


    Buttons on the receiver do nothing , I believe the keyring will fall off of the receiver very soon
    The receiver uses 2 batteries
    I believe it should use only one
    Not too loud siren
    Receivers not protected against water or moisture


    I just received this item . Did not bother reading instructions as usual :D
    It works great as it should . When you turn on one receiver LED starts blinking and the receiver is beeping , than you press one of the buttons on the transmitter . The receiver stops beeping .
    Turn on another receiver and press another button except if you want both receivers to respond on one button .
    I wonder how much the batteries in the receiver will last .
    The receiver has two chips (yes I just could not resist to open it ) , one crystal , and a resonator built in so the frequency is crystal locked around 433MHz .
    The build seems good to me , however I would not recommend exposing it to moisture .
    Great product , will order one more this instant .
    Thanx DX


    Thanx DX you did it again :D
    Will buy another one this instant
