Thank you for your feedback. We are sorry that you had an issue with this product. This tile cutter is best for cutting ceramic and porcelain up to 14" straight, 10" on a diagonal and 3/8" max. thickness. It is important to score the surface of the tile just once in one continuous motion. After scoring and without moving the tile, position the handle so that the breaker bar is slightly in from the front edge of the tile. Then, apply increasing pressure on the handle until the tile snaps along the score line. It may also help to hold the end of the tile while snapping.
