There are a few awesome things about this product. First of all is Geek Stuff 4 U’s insistence that this is a “soy sauce dispenser.” I’m not sure what will happen should you have the gall to fill it with something else, say honey or machine oil, but I wouldn’t mess with an astromech droid if I were you.
Second, R2-D2 is actually just one of the “flavors” of this dispenser. It also comes in R2-Q5 (or black) and R2-R9 (red). Both are still meant to be used for soy sauce.
Finally, this instructional picture, which is both unnecessary and wrong:
If you need a picture to tell you how to put soy sauce in to the dispenser, then after looking at the picture above you’re probably going to put a whole bottle of soy sauce into R2-D2. If you’re in need of a dispenser for soy sauce – and soy sauce only – Geek Stuff 4 U is selling the dispenser for about $40 (USD).
