It is true that the price put off at first. But tanks are great. Already it is quite large (it's hard to realize that in the photo but it's the size of a can or a mug in fact) and finely you can mix everything and anything !! And the fact of having four is excellent. We do not hesitate to use them, it is dishwasher safe and can reseal them to keep the preparation ... I do my ice with sugar, almond powder or hazelnut not to mention the salad dressings or fresh herbs. I also serve to make my pestos (green, red, arugula), to crush my Sichuan pepper after roasted to make bread crumbs with hard, short applications are endless! It is far more convenient to use the mixer for small quantities ... (and it does not stick to the bottom ...)
