Hello Nancy, sorry to hear you were having an issue with scoring the tile - which is atypical of this product. Although we have had nothing but positive feedback regarding this tool over the years, keep in mind that some tile types are denser than others, thereby requiring a little more effort when scoring them. Also, you will want to be sure you are not attempting to use it on tiles larger than 6x6, and no thicker than ¼" for optimal results!
