Having suddenly found myself living out of a room with my PC playing TV, I desperately needed a way to boost what is a poor signal to enable me to receive freeview.
After having tried a couple of contributed options (Indoor high gain aerial, different boosters) I was starting to lose faith, but I bought this on the basis of other users reviews. Much to my surprise, it works, and it works well. I now have a full compliment of 105 freeview channels, compared with 20 - 30 I had without this, and I get very little pixelation of the picture. On the more powerful stations (BBC, Channel 4 etc.) the signal is rock solid, and the only channel to exhibit any pixelation is ITV 4, and even then it's rare.
Signal boosters rarely do what they claim to be able to, but I have to admit that this one gets the job done.
