Head was broken after putting it into the dishwasher ONE time. it’s not for temperatures above 40 C (also not handwash above 40c)- so no way to clean it hygenic. I had to order the whole head (including the blades that were perfectly fine). That is absolutely not what they claim - to be sustainable by making it possible to repair every part of it. All of the jars (pretty normal mason jars and normal jars from the supermarket - e. g. from beans and pickles…) I had wouldn’t fit - although they all have the same size. So they say it is an ISO norm but in fact it was very hard to find a glass jar that fit the mixer. Mixing was average - if too little liquid in it, nothing happenes (I really hoped that this one would do better on this than the thing I had before). And lastly I got a very unfriendly, unempathic and unhelpful email from their customer service. I really loved the idea and the design of the product but the reality sadly was so different.
