I initially thought that the Natco 18 in tile cutter would suit my needs and, acccording to my research, it appeared better than a cutter I could purchase locally. About two weeks after it arrived, I finally had a chance to use it while installing tile at my weekend place.All went fairly smooth once the rails were lubricated and we cut five 12x12 tiles without a problem. On the sixth tile, we scored it well and then when "snapping" it, the handle of the cutter broke at the point where it attaches to the sliding rail scoring assembly. Examination of the break revealed the statement on the handle itself indicating that it was "Unbreakable". It appears that the handle is attached to a pot metal slider and that this weak material failed.Overall, I would not advise anyone to purchase this piece of junk. It's a waste of your money. Doesn't cut tile that well even when not broken.Well anyway, I got five pieces of tile cut before it failed. What a deal!
