Verrrrry nice product!

At certain time during a day, I need to concentrate myself into writing, but the surrounding environment was once not that friendly at that right moment, which was quite bothering. So I finally bought this signal blocker to help me get rid of those noise due to careless usage of cellphones and game playing. Now problem solved and my life is getting back into order again! Thanks again!


I recommend this jammer as well as this seller!

Reliable jamming of cell phones GSM 3G 4G internet and Wi-Fi signals. Besides, the price is lower compared to others. Good build quality.


Excellent value for money and quality!

The coverage area is as stated in the product description. And we can now communicate peacefully, and also control of children's usage of gadgets is assured.


Thanks! Now I can better manage my children's internet usage at

I use this jammer in our house. Now the children don't stay up late any more as they did before-- because their cell phones as well as the WIFI network no longer work as long as I turn on the jammer. Pretty helpful for me!
