Men's Health magazine says that Americans spend $2.5 billion annually on smoothies—that is, buying them at retail locations, such as Smoothie King and Jamba Juice. If you're a smoothie fan, then investing in an Oster MyBlend Blender ($29.99) might make a lot of sense. What makes this new product innovative is the fact that the bottle you "blend" your smoothie in converts to a portable, BPA-free sports bottle that you can take with you.
