  1. Major Dawn W.

    I love the reassurance of owning my shelter.We have somewhere safe to go, and I really do feel secure when the weather gets scary. We have used our shelter 2 or 3 times since we have had it, and I love knowing it is there.

  2. Christine T

    We love our shelter.The installation team made everything so easy. They cleaned up after themselves and even our permit was taken care of by the company as well.
