Got my 2pk in the mail yesterday as well. Pretty cool looking set. Someone might have addressed this earlier, but the wires on R2's legs are also different colored from the EB R2. EB R2's are neon yellow, while these are more of an orange/brown. Its cool to have the variations, but you're not missing much if you have the prior versions of these two in my opinion. I think the coolest thing about the set is the cool little premium black box they come in. I might actually leave these two in the package and just put the package up on the wall for display.
