When they say solid wood, they mean it.  The only particle board is present in the drawer assemblies.  Assembly was easy to follow along.  The provided allen wrench wasn't the best to use for some of the screws, if you have the same size bit to use in a drill or hand driver you'd be better off.  

Pros: Good finish, solid wood, easy to assemble
Cons: Wish they had tapped holes to mount the towel rack on either side.  Only mounts to the right side of the island (as shown)
