Fantastic 47in cutter! The rail is solid and doesn't flex at all; it's light enough to lift around. I had worried that paying £125 rather than £600 may mean poor quality but that is not the case. I tiled an 10' x 6' en-suite with 4' x 1.5' tiles without a single problem.
My one minor struggle was trying to align the laser accurately. I found that very small movements in the adjustment screw resulted in quite large swings. I ended up using it to roughly align the tile and then used the cutting wheel moved above the marks on the tile to make fine adjustments.
