This golden GSM signal Blocker looks good and is of good quality, it can effectively block the above frequencies. The price is also very reasonable, it is worth buying.

Very practical equipment, easy to operate. Great!

Very good product, it performed beyond my expectations. Such a cheap price can buy, worth the money.

I bought it for business trips. I was worried about being secretly photographed in the hotel or being followed outside. This jammer can prevent people with ulterior motives very well and makes me feel very safe. People who often go out recommend having one.

The jammer is very good and can turn on or off the corresponding frequency band according to your needs. The only downside is that the band switching switch is too small.

Compared to other online jammer shop, the price of this jammer is really cheap, highly recommended!

I bought one that can interfere with CDMA, DCS/PHS, 3G, 4G, and WiFi. It is mainly used to control the time my baby plays with the phone. I reached an agreement with my baby in advance to stop using the phone after 22:00, but there are too many in the phone. The temptation makes her always unable to stop. This cell phone scrambler is very useful, so that I don't have to worry about my children and affect our relationship.

I received the jammer yesterday and it is in good condition, small and not heavy. Really easy to put in your pocket or take on the go.

The delivery speed is very fast, it seems to be less than 10 days from the order to the receipt. The customer service is very patient to solve my various questions, the product and service are very good.
