I've got one I've been dabbling with. So far I've only had one complaint, and that is the pieces that fit on the inside to provide the shutters for the near-waterline guns. I just could not make them fit well and cut some sheet styrene to replace them with as I found that easier.
Otherwise, the hull is together, the aft deck piece is fit and glued in place. The rudder sticks out and can be a little fragile - due to the hull shape mine rolled out of it's box at one point and fell to the floor, which broke the rudder free, but it wasn't difficult to re-attach it. Some of the skylight pieces have large attachments points literally right next to small alignment pins, but I was able to remove the leftovers fairly well with a pair of flush cutters and clean up what they missed with a knife carefully enough to not lose the alignment pins.
One of the superstructure pieces requires two holes be drilled through, but this isn't shown as a required step in the instructions. I don't have the kit with me to know the part numbers, but you'll know it when you come to it as there will be a smooth top and the drawing will indicate there should be holes. They're on the inside and just need to be drilled through.
