I brought 3 of these to have one in each bedroom.
They make you internet signal worse.
Since I’ve fitted these plugs they have interrupt the WiFi signal to my phone when I’m in my bedroom, my daughters smart TVs from Netflix and give my son a bad ping on his Xbox I’ve had to disconnect them.
So now there just a plug with a flashing blue light.
They were a waste of money should have stuck with the double usb plugs and brought a better WiFi router.
