Fantastic product ... I have used the crystal-clear package for a nice and cheap case for that little 2.4 GHz bandscreening device Very nice and my banggood transmitter from my helicopter delivers the input. One can see the different channels which are using from it. thank you banggood for this cheap & usefull gadget.

This spectrum analyser does a scan of the 2.4Ghz Bluetooth/Wi-Fi range so you can easily resolve channel conflicts and find a clear channel. It works well over a wide voltage range (I've tested at 5V, 9V and 12V). It is good value and I recommend it.

This is a very good way to check a WiFi signal is being transmitted. It’s not sensitive enough to pick up low level background WiFi but that’s not going to interfere with much anyway. The size is remarkably small and light and it seems to work fine with power supplies over a wide range. I ran it up to 15V with no problems. For the price it’s a very useful device and easy to use. If you needed more sensitivity it might be possible to solder a short wire to the antenna on the PCB but I have not tried that as it works fine for what I need it for.
