I found the quality of the wood exceptional.  My 6 year old grandson (with me supervising) was able to put it together in about an hour and a half - that's how easy it is.  We did "weather proof" the wood prior to that.  I'm not sure how well the plastic tarp on the bottom will hold up.  I would have been willing to pay a little more if the cover was more than a mesh fabric which does not cover the whole area.

Pros: Ease of assembly.  Cost.
Cons: No bottom (other than a plastic tarp).  Mesh cover.
