The spike pegs really  arent sufficient the hold it in place during wind gusts. The instructions werent as detailed as they could have been as it has you attempting to construct it in an awkward manner. What I found was it was easier to assemble upside down pivoting from side to side with 4 people vs the recommended 2. 

Suffice it to say for the price its its worth it if you bare these tidbits in mind before hand
