@Catt Combs as I have indicated, we have matte quartz and this has not been an issue for us. It is very warm and humid where we are and this morning I laid my sweaty hand on the counter, leaving behind finger marks. Within less than a minute they were gone having dried. When I wipe my counters down with just water any marks are gone and the counter dries on it's own with no streak marks. I have under counter lighting as well as a lot of natural daylight and that's not been a problem for showing marks either. I do suspect however that you may see more marks with any counter that has more uniform colour. The more variation you have in your slab the less you will see any marks (mine has a very faint mottling to the colour). Also, Silelestone calls their finish "suede" and it has the faintest sheen to it which may also make a difference. I have seen other matte finishes that are more flat so maybe it's the NBoost that makes the difference.(in actuality my counters are lighter than this as you see in the above photo).
