Review: "I really do love this shaker. It's my favorite item I've bought this year. I use shakers all of the time and never thought of getting an electric one. First, this thing shakes! It really blends the powder well with water or milk or whatever you put in it. I love the colors, too, as it spins. just as a warning, some powders can get super foamy, though, but not all of my powders. Second, so easy to clean. So far, it hasn't smelled and I use it 1-2 times per day." — Rebecca
