Is anyone familiar w/this product linked below to get wireless signal around the farmstead, or even further the way it reads. Looks OK, but does anyone have experience w/it? Supposedly money-back guarantee if it doesn't do what you want. I'd like to get a Verizon signal out of the shop & into the house (300'+) and at the same time, into another little "out building". 2 of the buildings are metal & perhaps an antenna on the roof would do the trick?

Thanks
