Pretty good, they don't bother doing gun barrels etc. you can see and feel the layers, but they clean up well.
They seem to be very accurate and the Hunter for instance was in response to a request I made when he released his Type 26. He also quite happy to do individual bits from his designs, i.e. the ASMD mast from an ANZAC, or the Mk-13 GMLS and supply them separately for other projects.
