Reviews: Adjustable Cell Phone + GPS Signal Blocker Jammer

recommend rating

There are not really lot's of stationary and powerful GSM/GPS jammers. I've spent some time looking for those. I needed a powerful stationary blocker for A-GPS tracking system and I've actually got one. The choice was between this model and RCJ40-D, but I've chosen this one because it has a remote control and it's a little cheaper.
