The blender bottle electric works amazingly well at mixing powders!

　　The best electric shaker cup I've ever owned, perfect for protein shakes. Blends like a whirlpool! I have to recharge it once every 3 months.

　　The protein mixer bottle electric is very sturdy and easy to keep clean. Blends my protein shakes like a pro! A game changer for people who love superfoods, protein, collagen and every workout powder. No clumps, easy to clean! Easy to use, long battery charge time

　　I really like this protein shake mixer electric. make sure to clean it after every use! Rinse it with hot water and then rinse the whole electric blender shaker. The middle mixing blade is plastic, so I was worried about its long term durability, but for mixing powders it's great.
