Jammer Master レビュー 

The order came as expected and the item secured well. I had an issue with use of the product. Frank responded quickly and resolved it in no time.
Thank you.

Responsive seller, fast shipment, A+ product. I could not ask for anything more. Well done.

I purchased a jammer from Jammer Master about two months back, and I gotta say, I'm pretty pleased with their product. The delivery took around 10 days, which ain't too bad tbh, and I'm cool with it. What's slick is that they labeled it as a wifi router, so it slid through customs without any suspicions, no questions asked.
When I fired it up for the first time, it didn't do what I expected. My phone signal was still maxed out. So I shot them an email asking for some help. Frank hit me back real quick, and he told me to turn on the switch settings on the device, which I totally missed at first. After I flipped the switch, the machine work like an absolute charm. Thanks Frank!

The order was sent from China but their gear work just fine!

It's remarkably efficient and functions in utter silence. However, there was no user manual included in the package.

The jammer turned out to be a bit larger. Be sure to pay CLOSE attention to the dimension on the specifications.
