The equipment purchased for the company's large conference room works well in a space of 500 square meters.

The perfect jamming device, it shields the signal very well. Perfect protection for my private lab. Those who need it can start, and it is recommended to buy.

Just received it, the product looks a bit bulky, but the jamming works well. Neighbors about 50-60M away are affected, a good high power jammer product.

As described on the website, it can block all signals, which is very useful for me. Very satisfied

I received it and the test results are clear. With it, you are no longer afraid of being threatened, thank you!

It is very easy to use and install. It has been working continuously for more than a month so far, and the interference performance is very stable.

The indoor interference effect is very good, but the device warms up and clears the signal a bit slowly, it takes about 1-2 minutes, it is a small flaw, but for me, I have been using it continuously and will not lose power, so it does not affect me use. everything else is fine
