yeah
the red lights happened because the booster antenna wasn't getting a signal
when i mounted it outside everything was fine
the coverage of the unit isn't the best...but it does give me a good enough signal on the top floor
which is ok with me....
one thing to try before you buy is to put your cell phone outside where you think you'll be mounting the antenna....if you don't have a few bars in that location outside then the booster won't do anything
that seems to be there people are disappointed, this is a booster system you need to have a strong signal at the outside antenna location for it to amplify. if you don't have a signal it won't work
