I do recommend using a drill (mainly for the wood screws) as some of the holes are pretty hard to put screws in just using a screw driver.  Also, I did not notice until after I had the island assembled that there is damage to one of the sides on the bottom in 2 different places.  There is also what looks like to be a scratch that it looks like someone tried to color in with a sharpie marker.   Unfortunately, I completely assembled it before noticing this and you cannot return it after it has been assembled.  At least the scratch with the sharpie you cannot really see at all.  Besides the scratch and 2 areas on the side, this is a nice island and seems to be pretty sturdy.
