It cuts so easy , a D.I.Y must have . handles 600mm porcilian tile easily, straight and clean.the only problem I have with it is the cutter is not aligned straight and dose cut straight unless you mark at each end of the tile and make sure it`s going to those marks. I tried to realign the rail and got it to within a couple of mm and it is a pitty that I cannot just put a tile in and just cut it instead of fiddling around linnig up marks because the Rail is not square to the cutter.
