This product is really very bad !!!!!!!! ....... everything breaks, no need to wind or force to break braces, or twist the bars, the canvas is almost impossible to put, I do not even talking about the service, I was offering to pay to replace the braces and bent rod, almost a month after a reception, and without even having opened the package upon delivery. I took possession of my one month after arbor at the establishment that's when I noticed the poor quality of the product and believe me ... ah If no appeal !!! one ... pay again everything that breaks ...
