All the ceramic burred ones are much of a muchness for Espresso and not that flash for Plunger grinds.
There is a bit of an issue with them in that the lower burr is not supported above and below. At more course settings this tends to see the burrs moved off centre and hence a wider than desirable distribution of fines and course. That is not to say they wont grind for plunger just that they are not ideal and may lead to a little more sludge in the plunger cup. I have used the one that comes as part of the Grindripper package a bit for Travel pourovers and it still works plenty well enough but as it is going through paper no sludge.
My 40 year old Zassenhaus on the other hand is better at Plunger but not as good at Espresso (most likely wear in the burrs)
