The machine does what it should, if you is not too ambitious blocked this can not and you get back a clean cut. If you order only cuts cleaning, it's as smooth as silk, the masonry course no longer so easy. Concrete I have not tested.
The only major drawback is the dust arising at work, despite strong suction. Whether other machines, the better, I can not say. I am of my work of 20 years ago on the construction but announced that it has always terribly dusty in milling in the masonry and that too with very expensive equipment with extraction.
