I bought one of these sheds about a year ago to store my gardening supplies. Installing it on a concrete surface was not hard at all. You can assemble it yourself in one afternoon.

It is very spacious. You can get a wheelbarrow in with only one door open and you can store a lot of stuff. The plastic walls lends themselves to screwing any number of shelves and hangers so you can have your tools organized and accessible. 

I live in Southern California and our summers can get pretty hot and windy. So far this shed has stood up to the weather very well.

Very good quality and study. I would definitely recommend it.
