Portable Home Handheld Wifi Jammer/Signal Blocker

The Hand-Held Wireless Network Shield is a must-have for anyone who needs to block or jam WiFi signals.

You can use it to block any wireless network in the 2.4 GHz and 5 GHz bands, including Bluetooth, video, and audio transmissions. It also has a slow-start circuit design that will reduce the damage to your device caused by large current generated by the power switch at power-on.

This device is small enough to fit in your pocket—you don't have to worry about it getting in your way!

And since the Hand-Held Wireless Network Shield only blocks specific frequencies, you won't have to worry about affecting other electronic devices in your home or office.
