Don't get me wrong, the model looks really good: a lot better in person than it appears on the box. The function to move the arms and roll it into a ball are also very appreciated and, personally, I find the little droideka figure rather charming.

However, the model itself is not very sturdy when put together. It is rather loose around the "head" area, and there's not much securing the "piston" parts of the arms; they will snap off easily if bent a little too far, which is easy to do on accident with the ratcheted joints. Additionally, build process became rather frustrating when inserting the whip pieces(which are supposed to represent cables), as they refused to stay in place; I eventually got them to stay, but they do not feel very secure.

Again, it looks great as a display model, but it's not the most sturdy of builds. The droideka minifigure is also a bit unstable and easy to fall apart, even if it does look decent. Good display set, but best not to touch it much after it's done.

Would give this 3.5 out of 5 if Lego gave that option. I love the fact that Lego is giving adults high-quality, detailed display builds under $100. This is a major win in that regard and they should do more sets like this.

This particular one has just enough annoying about it, though, that it's not a smash hit. Some really finicky parts during the build with loose or odd fitting pieces, and a frustrating "minifig" that is also obnoxious to build and totally unnecessary, take it down a notch. Also, I'm not entirely sure the size of the droid really warrants a plaque—maybe I'm in the minority, but I don't feel like every adult-oriented Star Wars display set needs to have a plaque. I normally just put the plaque in storage.

No plaque and an MSRP of $50-55 to make up for the lower piece count, and this is a 4.5 out of 5.

This is my favorite droid in the Star Wars universe. The build is solid for a display piece. It feels like a nice size too, not everything needs to be a huge set.

I was excited about the mini model as well until I built it. It does not feel proportionally right. I'm not sure how to adjust that though. There is a bit of variety of this little droideka so I might combine some versions later to see if one works better. This one the arms feel too big.

The plaque display is nice (printed, not stickered) but I don't really have a space to display it. Still probably nice for some people.

I have been wanting Lego to release one of these ever since I first saw Star Wars Episode I. I do have the Technic version released when the movie first came out. But, it does not compare to this one. It is far more detailed than the Technic one. It is very sturdy for a droid set. There is some repetition, but not too much to bore you. The biggest flaw with this set is that they did not do a good job with the roll it in a ball mechanism. The Technic one was able to transform a lot better and a lot more realistic. Overall, I definitely recommend this set to any Star Wars fan.
