Bought it for a birthday present before the hogwarts castle and sound system came in. After playing with the sound feature for the castle, I wish I sprang for the sound system on this set knowing it won't just make train noises. Pretty happy with the customer service. The wires aren't as flimsy as they say. There was a few spots I snapped a piece on and thought, "well that's broken now." Only to be pleasantly surprised at the end. Would be easier to install if I didn't have giant hands, but challenges are fun, and this one I worth it!
