Super Shaker with a disadvantage

I use the Shaker to protein shakes after weight training to produce. Overall, I am very happy with the product. I particularly like especially the small doses, in which you can fill several servings of protein powder. These can then also very nice screws on the shaker and keep really good.

The only shortcoming that has the shaker is that the metal ball is not easy to clean. Just Protein shakes are sometimes quite sticky. And if you can dry the stuff, it gets harder. The cleaning makes really no fun. But for the shakes so much creamier than with my old Shaker. So I can live with the downside!
