If in doubt, try this out. I read the reviews, and on the strength of them alone risked the purchase of this item. It took five mins to install and within seconds found 99 digital channels, and we live in a weak signal area, off my main aerial I only get 72 channels, reasonably small and discreet and a really great price and I will be buying more. Remember you can always return it if you're not satisfied, I doubt very much you will be sending it back though. Five stars for a five star item.
