Nice, heavy base.  Arrived with a slight scratch in it but no big deal.  Would be better if the shaft was welded to the base.  It simply screws on.  A sticker on it reads that moving the base using the shaft voids the warranty.  If it was welded that wouldn't be an issue.  Moving this thing (77# thing) by squishing your fingers underneath it is ridiculous, that is if you value your fingers.  I figure most people use the shaft or umbrella to move it, it eventually breaks, and you have no warranty (but your fingers aren't squashed).  I hope it lasts a few seasons.
