Have this Bottle Order together with the Blender Bottle prostak. This one made for my friend, because they have a "cooler" impression, not this "neutral, narrow-minded" European design / processing, but just typical US-American. Priced it's just around 3 euros cheaper, but you can tell but significant differences in quality. Had here the many good reviews but I have to say for just 3 euros more you can get a much higher quality bottle. Here this is not totally bad, but that bothers me the thin plastic, it smells more like plastic (and are therefore more particles from?), The cover is very simple processed (but close), but you can tell: The product has been be given far less trouble than the competing product. Functionally, the result is however already: The shakes are thick, the cup is sealed. For me, the decision is clear.
