6 Bands High Powe Signal Jammer
Sometimes, we are often troubled by call noise or unpleasant songs or videos played on 4G or Wi-Fi networks. In this case, this portable jammer can help me stop these signals and stop unpleasant experiences, and teach them a lesson. I also drive frequently on business trips. Therefore, I have to use a jammer to hide my location to block the GPS tracker. I am very satisfied with this powerful jammer.
Review 6 Bands High Powe Signal Jammer
It also comes with a Velcro strap, so it can be tied to an arm or leg. It has a DIP switch, so any signal frequency band can be turned on/off without affecting other frequency bands.
This jammer is very suitable for use in movie theaters, shops and other public places. It doesn’t seem to work properly while driving (trying to block other drivers’ phones). When used for more than 10 minutes, the device does get hot (very hot). The battery can last for 1.5 to 2 hours. If you plan to buy a jammer for use in a vehicle, to interfere with other drivers' calls, please check the car device (not the portable device).
I was surprised by this wonderful interference. In fact, this is just what I need. Jammers now rarely include 6 antennas. I was lucky to find this item. It works well.
Portable devices do get hot, so make sure you buy a protective cover. It may not get all phones, especially cheap phones that people have used for years, but BlackBerry phones and newer phones are easy targets.
Special design and shape, effective blocking frequency range. Strong scope of work. Received within 4 days, just power on and test, you can lock my iPhone 8
After testing the interference distance and cooling system, I am very satisfied.
