SmartShake 2012 edition vs. 2011, colors are the not the only things that have changed

Slowly SmartShake stock is being replaced by 2012 V2 version of the plastic bottle. The color combinations are the most noticeable changes. Outside of the blacks, reds, grays and other styles the make has almost remained the same. The only minor change is that the grill seems to be made of a weaker, flimsier plastic. It still fits and works the same, probably just keeps the cost down.
