This is a great jammer!!! Each frequency band is controlled by a separate switch
Review 10 Bands Military Cell Phone Jammer
I am absolutely satisfied with my purchases and the speed at which I purchase them!
Recently, drones are always flying around the ranch, sometimes even hovering overhead for dozens of minutes, suspecting to be taking pictures. After consulting with my friend Jack, he said that someone might have been stealing information from the ranch, so I bought a low-cost but powerful drone jammer. Since then, no drones are nearby. Circling.
Great!! Just what I need. So cool! It worked better than I expected!
It's very satisfactory to buy such a jammer at this price. Its performance far exceeded expectations.
It's a Christmas present for my friend. He likes it very much!!!
Everything is satisfactory except the transportation speed. Great product!!!
