      It Works!

      Cell signal isn't the greatest here (1 bar mostly/ 2 bars if we're outside), so we started looking at options. Purchased this ZBoost booster hoping it would help. Put it up this weekend. It took a little while. We weren't aware that the exterior antennae had to be 15 feet vertical from the interior antennae so it took a little work to get everything right. Signal strength went up to 2 bars in most areas of our house; some places 3 bars. Some places still only a bar. But we are able to make and take calls in nearly every area of our house, which we were not able to do before. So while the signal strength doesn't seem to have been increased much, our ability to make and take calls is a lot better! As far as I'm concerned, it works!

      We bought this to boost our cell and data signals at our place in Northern Wisconsin. We were told we were in an ATT 'dead zone' but could get 4G and sometimes LTE outside. We have a mobile home, so signals were almost nothing inside. After installing, we get LTE and 3 bars everywhere inside. I had to construct a PVC pole to get it 15ft high, but the small antenna and bracket hardware made it easy to attach. I used different sized PVC that I could telescope to get high enough, and when attached together and to bracketed to the trailer, it is very sturdy. Set up was easy...once plugged in it did everything automatically. VERY HAPPY. Now we can cancel our expensive landline.

      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.

      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.

      Booster Greatness

      I live in area in which I have only been able to use one cell service unit I purchased this booster. This booster improved my signal from one bar to five bars and now I will be able to switch to any cell service of my choosing. This booster is a bit pricing but in the long run I will be able to save money because I will be able to select a cheaper cell company. Thanks BestBuy for offering this booster....

      We live in a rural area and the closest cell tower is 10 miles away as the crow flies. We live in a metal building with a metal roof. Had zero bars inside until we installed the zboost. Now we have 3-4 bars and we are back in business. Thought I might need a multi-directional antenna but the basic antennae works just fine.

      We have lived in our home 25+ years. We've never had good service inside our house. There was 1 place in the kitchen you could stand to make a voice call. We installed this yesterday. We have 2-3 bars through most of our house now!!!!!

      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.
