Now that I have this cell phone jammer I can see why it has so many good reviews. Before getting the blocker we had 30 to 40 unwanted calls a week. Once I use this device, I will get not one call. Since hooking it up one month ago I have manually blocked 11 phone numbers and 19 area codes and I keep getting fewer and few calls. I cannot believe it took me so long to find this device. We had been suffering all the abuse for way too long.. I cannot imagine living with out this product now. Now I can enjoy a quiet dinner
Review 4G GPS Signal Blocker
The shielding effect is good, and the concealment is good, very satisfied
It works perfectly, but it's actually pretty good. There are cheap things in other stores, but I'm willing to spend a few dollars more for this.
