Any experience with Wilson 4G 700Mhz Repeater/amplifiers?

OK,

I just moved to a new neighborhood. I no longer can grab a solid 4G signal in my house, except when I go to the third floor and hang my phone out the window (about -95Db in that case). I'm contemplating buying a Wilson 4G repeater kit. They seem to have some good reviews, so I don't think it's a gimicky "TuRBO-SigNal-Boosterz!" type of product.

Anyone have any luck with something like this? I'm really trying to avoid giving in and subscribing to Time Warner Cable, so any encouragement would be great.
