Yes, it inevitably does some odd things but it's pretty amazing given that it's automatic. Here's a sphere with some booleaned holes. Simple in Moi but quite hard to do something like this in an SDS modeller and keep smooth surface continuity. This is Modo's viewport with reflection shading which is good for detecting kinks and pinches in the mesh. Very impressive how ZRemesher tries to flow polys radially around the openings. A bit more work with some guide curves and it should be even better.
