Reviews: Handheld 4G Lte 3G Cell Phone Scrambler with Individual Control

recommend rating

While it's a bit bulky, not really something you can carry in your pocket putting in anywhere exposed does the job extremely well. I'm on a floor which is much larger than 20Meters and is all open floor plan, I turned it on and sure enough within a few seconds people were looking at there phones with that dumb look on their face trying to redial over and over until they realized they had no signal lol. I would recommend this jammer for sure. The only issue I noticed is that with T-Mobile the service didn't go out to 0 bars, went down to 1 but wouldnt place or receive calls, 4g went offline asap.
