Ordered this on Thursday.  The granite top arrived on Saturday and the base arrived on Monday.  Excellent shipping and delivery times.  Packages were very carefully packed, with the granite top arriving in it's own little wooden crate, with layers of foam and corrugated inside to protect it.
Assembly was pretty straightforward.  I must say we never, ever do it right the first time.  When assembling the shelves, make sure you have the proper side panels facing in the proper directions.  We had to back track a bit, but managed to do so without too much heartburn.
We recently redid our kitchen in shades of black and gray.  This island is the final piece of our renovation and we are thrilled with it.  We'll definitely shop Wayfair.com again for anything we might need for our home.
