I ordered a protein shake from Powerbar and even though I knew that these were actually always quite readily soluble, I wanted to have a shaker to. Because of the good reviews, I decided me for this and I have to say: WOW! Shake No long and everything is super dissolved and creamy ... the cleaning works flawlessly! Just add water and some washing up liquid in, by hook, finished :)
Among the other reviews: so I ordered the Shaker Amazon directly and he looks like in the picture. I also find that it can be seen in the picture that it is not here to clear plastic, but this is slightly darkened.
For the price an absolute top product! Stable, efficient, super result, easy to clean ... what more could you want? We recommend!
