Our piece took one month to arrive...a little longer than I had anticipated. The packaging was extreme to protect the pieces from damage. Unfortunately there was still a minor ding on one of the panels (that can be seen if you look closely). There was also a crack on the inside of one of the pieces but it went together fine and it didn't seem to effect the structure as a whole. 
Building the island was absolutely straight forward. If you can build an ikea dresser you can build this! All of the holes lined up, and all the pieces were present. It took my husband and I about 2 hours (the first hour was myself alone). Overall we were quite pleased and have had many compliments on the island. 
I was unsure of the wood top (as the granite was sold out) - but it is quite nice (not cheap looking). 
Absolutely would order again from Wayfair.
