SmartShake is made from high quality industrial BPA & DEHP free plastic. It is safe to use in micro, freezer and dishwasher. Thanks to the advanced anti-leak technology the lid and the cap is 100% guaranteed leak proof even for hot and ice-cold drinks. The key benefit with SmartShake is the storage compartments in which you easily store several servings of nutritional supplements. Such as protein, creatine, vitamins, capsules, pre- & post workout supplements or pretty much anything you like. SmartShake gives you the freedom to carry around everything you need for the whole day, all in one unit! It is much more convenient than carrying the alternative; three individual shakers, or worse three tubs of your supplements. You can also store berries, fruits, yoghurt, cottage cheese or even cook oatmeal in the microwave oven with your SmartShake. The innovative and concave strainer mixes the powder with liquid to perfect viscosity in just a few shakes. The strainer snaps on to the lid (patent pending), no need to get your hands messy every time you want to lift the strainer/mixer.
