I purchased this to increase my signal at my lake house.... the unit does work, but is totally unreliable. There are times when the lights go red, red flashing, I've tried all manner of things such as changing the position of the antena etc... I even called their customer service, for all intents and purposes, customer service sucks. I would NOT recommend purchasing this unit. It is not stable at all, I would have done just as good if I had taken my hundreds of dollars spent, and lite fire to them. I am and EXTREMELY disastisfied customer.
