"I just bought this set and built it. The build took around 4 hours and it was totally worth it. There are 9 bags in all, most of them are relatively big. The most difficult part of the build was the treads, and if you are a young or amateur Lego builder then you may need some help. The end result is great, and it is very large. You can fit all the minifigs plus a couple more into the interior. The interior itself contains a spot for the Jawa speeder, plus a control panel and crane that can be used to lift the astromech droid or the crates. There is also roon to store the droids plus a cockpit or steering area for the Jawa to control the Sandcrawler. The treads can turn via a knob at the back. Overall I recommend this set to anyone who wants a challenge or wants to learn basic and advanced Lego building techniques."
