QEP 10630 24-Inch Professional Manual Tile Cutter with Tungsten Carbide Wheel - Perfect for Porcelain, Ceramic Tiles - Ideal for DIY Home Renovation, Bathroom & Kitchen Flooring Projects

I tried on a 24 inch porcelain tile, every cut is a perfect cut except the very first one. Very quick, very clean -- much more clean than wet saw (and this is the main reason I look for a manual cutter).There are some lessons:1) Cannot press the middle or any part away from the end point, you will crack the tile, 100%. Only press the very end part of the tile.2) Cannot cut one side too narrow (less than 1 inch in width) and other side is too wide. The press is about 2 inches wide it will not apply any pressure on tile strip narrow than 0.8 inch.Other than these, I can say every cut is a perfect cut. Comparing to wet saw, you save a lot of time, and save a lot of effort to clean thereafter.
