This is a great set. This is also my first star wars set. The building prices is not that special. But there is a LOT of colors in the inside of this droid. Why? I have no idea... The final model is really well designed. The little functions like r2's disc cuter are great. To retract the there leg however is quite a process. It wood also have been great if it had wheels under it. But you can easily do this yourself. Ratings: -build 8/10 -valu for money 9/10 -over all 9/10 (wood have been a ten if the third leg was a little easier to extend and if it had wheels under it.)
