A great shed for the money!  When I opened the box, I was a little skeptical. The material is a corrugated plastic, not the thick vinyl I thought it was. I didn’t think it would be very sturdy, but I was pleasantly surprised how sturdy and easy to level this shed was once the roof was installed. 
My 13 year old son and I put the shed together in approx 2.5 hours. 
I would recommend this shed to anyone who needs a place for lawn mowers or snowblowers etc. I would have to suggest this for light to moderate traffic/use.
