Why would you want one of these?
It doesn't use your wifi, it forces you to use a network specific to the device, so you can't use it and your network together (unless you happen to have a device with two radios as they helpfully point out).
It would need to retune if you take it anywhere out of your xmitter range (roughly 30 miles from where you last tuned it).
A rabbit ear is not going to get much of a signal where I live (Oxfordshire) and I suspect most of the non-metro bit of the country.
It requires a TV licence, or will shortly if Capita have anything to say.
Clearly, marketing to the fondle slab owners is their one hope.
