Was a little worried about logistics company but the online service from top signal jammer was top notch fast responses and definitely helpful and am very satisfied with the product

I put it in my car because I was worried that I would be followed by my wife to date my lover, it turns out to block GPS locators, highly recommended! ! ! ! !

Very effective, small and delicate, I love it!

It worked so well I plugged it into the cigarette lighter port on my car because I bought a mortgage car!

I bought this GPS jammer and it works great and has a built in battery that I can put in my pocket!

Jammers are very convenient and can interfere with various frequency bands. And turn on or turn off the corresponding frequency band according to your needs. The only disadvantage is that the frequency band switching is too small

The jammer can run continuously for 24 hours. Using aluminum shell, good heat dissipation. The interference range is larger. It's perfect for me to use it in my apartment, I use to block cell phone/GPS/wifi/RF signals from entering my apartment.

This is an excellent signal jammer. It is very convenient to carry and can interfere with signals in many different frequency bands.

This is a very efficient portable jammer device-portable and practical, with an antenna. Whether I am on a train, in a movie theater, or where other

I bought this jammer a week ago. I chose it because it provides me with a wide storage frequency, so I don't need to complain anymore.

Review by Carriou P. on 12 Oct 2021review stating The product is greatThe portable jammer I bought, the website says that it is shielded for 40m, I tried it, and it was only about 35m. I am very satisfied.

This is my first time buying a product from topsignaljammer, and my communication and my value impressed me. The 16-band jammer works perfectly in my 25,000 square foot warehouse and keeps my employees working without having to text or call. Thank you! !

I bought it because I was going to use it in my car, it also comes with a cigarette lighter port, it does exactly what I need, and the jamming distance is great!

It works exactly the same as advertised. If the distance is close enough, BT will also be eliminated. The sales staff and technical support are really great. Don't let the lack of purchasing options scare you. They ship the fastest, the fastest I have ever seen. The product comes with a very beautiful box, magnetic lid and world-class packaging. It has a very good structure and is obviously proud. They are honest people, and they provide honest products at reasonable prices

This thing works well indoors. It works well in restaurants, but sometimes it takes a minute to eliminate the signal. An office worker stammered outside with his mobile phone for 20 minutes. I think it's time to go back to work. Turn it on, she was ten yards away, and killed her phone in just a few seconds. It doesn't work well in my car, but it may be that the windshield is blocking some signals. For some mobile phones, it can work within a few seconds, while for others, it cannot work. I like to interfere with the cells of some of the women driving if I buy a more powerful device.
