I reluctantly give this 5 stars for two reasons. The first being that for the price that I paid for this the quality control could have been better. For instance, the first wall that I put up did not lock into the floor, the side windows that allow for light did not fit and had to be shaved down. One of the side windows had the manufactures writing, which should have been facing the inside of the shed instead of the outside. In some pieces the screw holes did not match up. The two pieces of the floor were off maybe a bump, which had me worried that it might affect the alignment of the walls, but it didn't. The other thing is that I don't see the floor as being that secure to the floor, basically someone with a prybar could get in by prying the shed from the floor.
Suncast does point out that the shed is not waterproof and that is obvious, but I think they are talking about if runoff from a large amount of water. I was able to fix the problems, but it took more time. I did secure the floor better by buying some small brackets and attaching them to the wall and floor. I also bought some adhesive waterproof tape to stop water coming in from the sides around the floor.
As far as the positive aspects of the shed. I bought this shed in January, but I wasn't able to put it together until mid April, as I was waiting for weather that wasnt so windy and I also needed to build a foundation. One of my concerns about waiting so long was that I was hoping that all the parts would be there and they were. I would give the instructions 90% out of a 100%. I am also no spring chicken and I was able to put the shed together by myself.
I did have doubts about this shed being sturdy as I was putting it up, but when I completed the shed I was very pleased at how sturdy it actually was on the sides, doors and roof. I would caution against leaving the wall and roof side up for too long of a period. I did that when I first received the package and pulled everything out of the box and when i went out the next day they were bowed a little bit. I laid everything out on top of the box and threw a tarp over them. The pieced did straighten back out and once everything was put together I haven't had that problem. I did buy the light colored shed, but I don't know about the wisdom of having a black roof, especially in areas where the heat can be brutal in the summer.
Overall, I am happy with the completed shed. Although, I still had to add brackets to the floor and waterproof the bottom. The shed looks like it will last awhile and it looks good.
