Unfortunately when we arrived at our camp site and tried to set up our Shelter, the pressure gauge on the pump did not work at all. So despite all of the warnings we were unable to pump it up with any knowledge of how full it was. We had no other shelter so had to go ahead. The shelter itself is an absolute WINNER. We loved it. Although I'd say the door openings are a little low for a tall person and we would love to be able to buy a floor for it. We bought all the walls and experienced extreme heat, rain and winds. It stood up to them all perfectly. Worth the price, even though its expensive. Waiting to see if Tent World will replace the pressure gauge for us.
