I've used the two Wilson systems over the last six months. One was a mobile unit and the other an extended small office unit. They have both done a good job as intended.The basic problem was a fringe range area just outside of cell phone reliability. I could get calls outdoors, but nothing indoors. It was just on the edge.The unit runs well even when not hooked up exactly as recommended. I have used a mobile antenna taped to a window and the in car antenna for the relay. This works. I've also got the dome interior antenna and yagi for improved performance. These are in waiting for implementations.Easily improves calls. Have used on Verizon service.We also use this unit for two co-workers homes at the office. Both perform well and as expected.
