To start, I had an AS for close to 19 years before needing to replace it.  Wow! right.  Ordering was a breeze and was  delivered promptly.  Now comes a small negative.  How the AS is packaged.  The cardboard box split in transit (was taped at some point) and the frame poles were loose.  They should be tied together some how, maybe zipties, because the pieces were sliding out of the split side of the box.  A very heavy (270#) box.  Other than that all was good.  Love my AS and hope to have this one for 19 years.
