I have already been juiced berries and am completely satisfied with the result. The juice yield corresponds to the manufacturer's instructions. Only problem was the clamp that are not firmly enclosed the tube, so that the beginning juice expired. I resorted to reason with the bracket of my old device. Moreover, I find the recommendation to give the sugar into the collection vessel, not good. He let go there on only in part. I will the next time the sugar again, as in the past used to pour over the berries. Otherwise the juice schmekte very good.
