So far, it's a pretty good cell phone jammer.



I just got this jammer and it looks great, the signal I hated is completely blocked. I like it very much.

Kelvin Ho


A friend recommended me to buy it from jammermfg. The product is as advertised on the website, and the effect is very good. Friends who want to start can start. The products and services of jammermfg online-jammer-shop are good, guaranteed quality and trustworthy.

It works fine. I hope it works for a long time as it does now!



This product is great and works right away! It comes with a nice protective case and car charger. I highly recommend this cell signal blocker.

Having tested it, I can say that it exceeded my expectations for range and effectiveness. Put my laptop in the same room as the router and phone, with one end of the room and a signal jammer at the other. Even in a few walls and rooms, the laptop was not able to surf the internet normally. very good!
