It does what it says but it doesn’t block gps tracking 100 percent. I use it when I need to but, for Instance, If you use it on a 10 mile drive, it will occasionally show your location along the route and when you come to a stop, it finally pins your location after a minute or two. I’m not complaining, by any means. It doesn’t do exactly everything I want it to do, but it works for the most part. The biggest problem we have is they track out speeds and see if we are speeding, but I was hoping it would just show me at the last known location permanently until I unplug it.
It’s a great little jamming device and does most of what it claims. I would like to try a couple others, like the original one that the blue jammer replaces, as you suggested the blue one was an updated version. I would still like to try the earlier version (the one with the lcd window on the unit) as well as some of the others, which I have ordered in this recent order.
The only drawback I have noticed is that it interferes with my cellular device communicating with the Bluetooth audio in my vehicle. That makes hands-free communications with my coworkers a bit intermittent and I have to unplug it while I’m on a phone call, which is a tad bit aggravating, but it is fun to use.
Another thing is this device does get really hot while plugged in, but I assume you have tested these devices and this thing has some sort of internal heatsink on the internal chips that allow proper cooling. Your product is great and I am going to try a couple more. I have already given your website address to a couple coworkers because they are interested in purchasing some of these as well.
Thanks for all you do.
