Has anyone had any experience with Wireless HDMI Senders? I've been reading a few reviews of the technology on the internet and they range from brilliant pieces of kit to a dead technology, so I was wondering if anyone has had any experience of them? I'm looking into having a TV in another room of my house on which I can watch and control Sky without the Multiroom, and hard wiring it with the magic eye is not an option. Also seen that you can jack your PS 3 and other things into some of the senders and control those, which would be ideal for what I need, if they are any good.
