Works brilliantly only down side is it comes with an usa style usb wall plug but luckily i had an adaptor so enjoying purchase i have to start by saying i have a smart tv and takes it even further on the basis of streaming and connectivity

The hdmi connector plugs into a spare hdmi socket on your tv and then you plug the included power wifi antenna cable into the other end

For power you need to attach this cable to a usb power source of at least 1a i have a usb port on my tv but you may need a separate wall charger for some sets

If you’re wifi signal is having difficulty reaching behind the tv then you can give it a boost by repositioning the cable antenna
