    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 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

    Very cool for the price! Works very well from a 9 volt battery. Not very sensitive, but you certainly can see that your device is transmitting and you can see the channel from the spectrum.

    Leider war einer Defeckt also dann zu teuer. Die Recklamation artete in Zurückhaltung aus. Was soll ich da Fotos senden oder Video wenn das Ding nicht läuft. Wie es aussieht wisst Ihr ja. Der Andere läuft aber ist unendfindlich, Ausschlag von einem mm beim Abstand 1m bei 0,5 Watt.

    Ok, tutto bene. E' un piccolo strumento che, dato il costo davvero modesto, funziona inaspettatamente bene.
