zBoost - TRIO SOHO Cell Phone Signal Booster
I am using this at my cabin, it seems to work a little better than my old one, not exactly 2500 sq ft coverage as advertised. I may need to move the unit & antenna around later to get a better signal.
The antenna and the base unit need to be as far apart from each other as possible, ideally, straight up on the roof as high at you possibly can to get the best signal.

So far so good
Item just arrived today, but quickly installed it with the outdoor antenna sitting in a window, and the results are immediate and significant. We have a metal building for an office, and it sits in a very low lying area. If we want to use a cellphone we must walk out front. Placed the antenna in the front window and set the indoor amplified antenna just 20' away and we have boosted signal by 3-4 bars for everyone's cell phones. AT&T, VZ and Sprint users alike.

Works well for us.
My setup of this is temporary but it has GREATLY improved the cell service in my house. Easy to set up. I knock off a star because I have to unplug it and basically reset it every couple days. Not sure if this is the fault of my setup or the unit. Works well when connected though.
