Has anyone used Farrow and Ball dead flat?

[Kjdh21]

I just cannot find any reviews of dead flat finish. I am considering either little greene or Farrow and Ball for the whole house. Is dead flat any good for high traffic with children? Does it mark easily like the other finish they have?

I have used both finishes, the same paint colour in two different rooms - not much difference on the walls.
I have also used it to touch up my kitchen units - the lack of sheen makes it brilliant for this purpose. It's a rough texture - so I'm not sure about it wiping easily and I don't think I'd use it on wood. I prefer Little Green - it has better coverage.

I used it years ago on skirting boards. Great finish and didn’t chip, or look scruffy, even though it was a dark colour.
