Only used for 1 season . It does have a couple spots that show some wear but heats up well with no concerns affecting the overall warmth of the house. All zippers, windows & pole system work as they should. It has one very small hole the size of dime that goes thru it and the other spot on top didnt break through it as auger blade cover came off pulling it across the ice. It comes with all support poles for it. Cash Only Thank you for looking any questions let me know
