Very easy to put together, simple, clear instructions. Looks great when finished! Couple of helpful suggestions. One, the model comes with 7 blue plates that act as the base and simulate the ocean. You do not need to attach the first plate as it contains only the iceberg, which you can build last in any shape you want. also it allows you to use some of the clear pieces to make a stronger connection to the other plates than the instructions have. Second, the manufacturer gives you more of the clear red single pieces that act as windows than you need per the instructions. Count how many you have and you could use them to add extra where the model just leaves a space. Just make sure you have an equal amount for both sides. Over all an excellent model, great price and fun to do. Well worth it.
