The shelters are awesome! They take 2 people about an hour to set it up, using the 120 volt supplied air source, a vehicle to help pull it into place while it inflates and about 250 gallons of water. Once erected hose it down with water and wait 24 hours, it's then ready to go.
There are two sizes available a 580 sq ft and 270 sq ft models. The 580 weighs just shy of 7000 pounds and costs $31,600. The 270 weighs just shy of 4000 and comes with the price tag of $25,259.
They aren't portable once erected and require a forklift to get on site but once erected are bullet resistant fairly weather proof.
