I bought the 8 x 15 dual door and it has been up for over a year. Made it thru winter and rainy spring with no problems, Shed looks great , it 2 took senior retires 2 days to put in together, just take your time, folllow direction and make sure your floor is LEVEL.  If you are having difficulty you  just go to U-Tube. Highy reccommed this product [This review was collected as part of a promotion.]
