"An amazing purchase! Obviously it's quiet expensive but I believe it's great value for money. I'm 21 and it took me 15 hours and 28 minutes to complete in a relaxed way (multiple sittings in front of the tv). It has 14 stages, taking between 45 mins to 2 hours each (average of about an hour). The finished thing is very heavy, and is ~49cmx33cmx75cm. It has so many cool features and a secret chamber. Not to mention a thing to shoot "fireworks"."
