Very good cutter. Years of delivery by roubi. As mentioned by a friend in a comment. It struggles with some tiles (but it has to do with the quality of the tile). The problem it caused me is that when I remove grout at 120 on the bottom side, it may come off a little (a millimeter) resulting in not all being the same. But the problem was solved with a pantenta (second guide on the bottom part).

Here we go. Good cutter but in grade A tiles, generally in tiles that have a problem with baking, it breaks wherever it finds a weaker point. I used it on 120x60 dimensions in both A and B grade granite tiles. The B grade broke wherever it found. The A grade broke where it scratches with 100% success. I also used it on 60x60 and had 100% success again. One construction mistake I found is that it has 2 plastic points at 0 and 120 where you break the tiles after you have scratched them. If they added one more in the middle, it would be better so you can also hit in the middle since you cut the 60 side. In scratching, it doesn't require literally any force because it has the big diamond and the cutter has a lot of power. It's worth getting. I have 3 in my possession
