I drink a protein shake in Fittnesstudio like after training I wanted to come also to benefit and at home to enjoy a shake of Inko. The Royal Catering Shaker is a very good device with the protein shake with to 13,000 revolutions is entirely convincing and surprisingly good shakes manufactures as in the gym. Very creamy and tasty. The shaker is very stable and the cleaning is very easy. Simply make a sponge the rod clean and then again, "shaken by" with tepid warm water. Finish clean the rod.
