I’ve seen dry food savers advertised on cheap TV ads with a similar ”accordion” shrink concept. This one, as is usual with Dyson, is a lot more technically sophisticated.

It does appear intriguing, but as with those other squashable plastic containers, there is the cleaning issue. Have to see and handle one in person.

I wonder at the kind of plastic being used? Even extended, the inside walls might have uneven edges that would require careful scrubbing?

Since the purpose is to be able to keep milk longer, that means an increased possibility of bacteria growth, so thorough cleaning before adding milk would be even more important. And if the plastic is not top quality, it might leach BPA or other chemical? into the milk.

I’ll be waiting to hear what users experiences was and testing of milk over time. Clever idea though.
