The Sundesa Blenderbottle with Blenderball is a simple gadget designed to help you blend things without electricity. Inside the 28 ounce BlenderBottle is the patented stainless steel BlenderBall wire whisk. Drop the ball in, put the lid on (very important!) and shake. The ball mixes even the thickest of ingredients and stays put inside the bottle.
The bottle is useful for mixing up protein and meal replacement drinks quickly and easily. You can make them anywhere. It’s also ideal for mixing pancake batter, salad dressings and marinades, or even adult beverages (margaritas baby!). Great for camping too. BPA-free and under $7, this looks like a good buy.
