    Ordered the blocker mini but found out it does not block iOS devices. Got in touch with the sales team and they squred me away with one of these as an upgrade. Works really well!

    When I first got the unit, I really didn't know how to use it. After emailing back and forth with support (Thanks Carl!), I was able to finally figure it out and have been able to use it successfully.
    There are no instructions that come with it, but they are online. Since I used to write technical manuals, I re-wrote them a little for myself because now I am going to purchase 9 more units. I may go for a larger, professional unit though..

    I used one of the mini units for years, but noted a lot of 4G signals were not getting blocked, so I upgraded to this. I miss the little unit with no antennas sticking out, but this one is small enough to fit in my pocket without much bulk and it knocks down all the signals.
