Query: Nice idea, poor quality, poor performance

I agree with the other reviewer. I saw this as a closeout in a tool store and bought it because it was a traditional style with hole cutter. After I got it home and set it up, I messed up my first tile and that was enough. Score performance is poor due to binding rails and shifting tile, making the score line waver. Breaking ability is also poor with lots of flex in the base that causes the tile to break incorrectly.Overall, a very poor quality piece of junk that delivers poor performance. I am returning the unit today for a refund. The same unit is sold under many sites. Avoid them all.
