Good points: -They milled my complicated project that was rejected by other services. -Their staff pointed out my error and suggested several solutions -Mail responses were quite fast -Quite reasonable price Things better to be improved -Some points milled too much -I ordered surface smoothness as Ra1.6, but couldn't tell the difference between those with the default setting. They were not so big probrems for my way of using the product and the extra cost for surface smoothness increase is quite cheap, so it was okay this time, but if I want more sophisticated product, I would look for a better service.
