    This product is very cost-effective, because I have seen many products with 5G frequency bands are very expensive, but this product is very cheap.

    I purchased this product for testing in our security facility. It blocked the battery, Bluetooth and RFID in my initial test. Now, this is the very good part. Cell signals are more likely to be blocked, but Wifi is much more difficult, especially near routers. The signal strength may be high. The device can block 2.4GHz and 5GHz Wifi at the same time. I recommend recommending this feature to the upper class, especially because the staff can add business cards to the sleeves on the back of Velcro.
