This wouldn't be so bad if the connections were standardized, but every manufacturer has their own standard, and sometimes don't even stick to it across their own products.

If this was standardized, you'd just buy a new blade/connector or jar from whoever, and in fact you'd have a wide choice of specialist jars and blades to choose from.

The concept of re:mix is great (and the name), but at €350 it's irrelevant. Make the standard open and free, maybe get EU persuade it's use, and let manufacturers build around it at realistic prices.
