I was intimidated by the many pieces at first and thought this would be flimsy.  But, once I got into the  project, it went very well.  I only needed help with putting the roof in place; otherwise, it's a one-person job.  I did it by myself in about 6 hours and when everything was screwed and in place, it is very sturdy.  Fits a bike, a lawnmower, wheelbarrow and all my gardening tools.  I like it very much and am glad I got it - perfect for what I wanted to store in it.  
I did spray all the screws first with Rustoleum to avoid the rusting problem that another buyer mentioned.
So far, it has held up very well to several wind storms.

Pros: Not too big, not too small.  Will never rust, nice addition to the yard.
Cons: Haven't found any yet!
