    Use it!

    posted by Tessa25 on 02/03/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    It is small. It has very light weight. Good colour - black is suitable for such kind of things. It is easy to mount antennas. It does what it is suppose to do - it blockes the cell phone signals (both 3g and gsm).
    Cons:
    It has not very wide radius of its effect. You have to be in the same room with the device you want to block signal on. Someti...

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    I use it someimes for fun, or if someone annoys me talking too loud ar too long on the phone - I just block the connection - and the person hears the silence. Works very fast, and blocks all signals quick. It also blocks local phones on my work station at ...
    Cons:
    The radius of working is not big. You should be at the same room, or the walls should be really thin.

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Made of metal Easy to operate- you have to be a moron to screw this up! The device turns off when done charging. Battery life is really really good!
    Cons:
    Antennas broke after awhile. I dropped it so it's my fault. Besides that, no real problems.

    Cons:
    Becomes a little hot when turned on, and placed in my inner pocket. Would have been better with larger range, but i can't compl...

    This is a fun little phone blocker. It works as expected on blocking the GSM signals with 5-10meters for me. It seems well built for the price and has nice feeling to it.
    Cons:
    3G does not work at all i think the output power is not strong enough and battery life is a little over 3hours on a full charge...
