Effortlessly Protein Shaker Powder Supplements,Eflar Electric Multi-Purpose Portable Shaker Coffee Stirring Bottle Mixing Cup Electric Self Stirring Coffee Mug 450ML - Blue

Bought as a birthday gift for my mom. Came a little off time but the product is perfect. Also is waterproof.

This thing eats batteries, and the motor doesn't mix very well. I used it 3 times before the batteries (not included) died. My normal, manual shaker does a better job mixing my shakes.

Mixes light powders well; however, battery power is drained quickly with consistent use. In need of a more energy efficient motor.

My fiancé loves it! Perfect for his protein drinks.

the bottom does not detach so you have to shake it to really clean the internal mixer arm.

Was a gift. He liked it.

Cup works well, but the top ring collects the fluid and can't be cleaned!

Great product
