It's short, but possesses the power of the force.
Why is it that nobody makes something like this full sized? R2 wasn't really all that big, and if you're going to go to the effort to create such as detailed (and functional) recreation of the droid, do it 1:1 scale.
If this were 1:1 scale, I'd buy two (one for home, one for office). Although I'd probably repaint one R2D4 or something..
