2. Oster My Blend™ Blender ($30; www.amazon.com)
Why we like it: Mixing delicious protein-rich shakes or fruit-filled smoothies may be smart when watching your weight, but there’s nothing fun about making them—until this little wonder. The Oster My Blend lets you whip up what you need, then you simply detach the blades, place the lid on the bottle, and voila—it turns into a portable sport bottle so you can drink right from the 20-ounce container, or, bring your shake with you to the gym. You can even use the scratch-resistant, BPA-free plastic bottle all day long as a water bottle once you’ve finished your shake or smoothie.
