Installation and setup of the wireless extender was as easy as purported. However, I'm having a hard time determining whether I'm actually getting any improvement in cell reception while in my home. Voice quality during calls is still only fair to poor with lots of garbling. And I still have instances where someone tries to call me and the call goes straight to voice mail without ever ringing my cellphone. I had hoped the extender would overcome some of the inadequacies of cellular technology, but that seems not to be the case.It's interesting how bimodal the reviews for this product are: folks either love it or hate it. Based on other reviews and my own experience, it would seem to be a good product in applications where there is a significant difference in the signal strength outside your home vs what you get inside. That is, if you get 4 bars outside and only 0 or 1 inside, then this may be worth a try. On the other hand, if you get a decent signal in your home and you're just trying to improve call quality (as was my case), then take a pass on these extenders.
