Ive borrowed Widlers 1200 sigma withe the klick klok system for the last couple of weeks, it's an awesome bit of kit, a beast to carry about but it's pure quality and cuts 1000x500 rough faced porcelaine like a knife through butter, even takes a 20mm cut off the 1000 edge no problem. Iwas a big Rubin fan till I bought one of the new TP cutters, which is bugged up as their new porcelain cutter but unfortunately it struggles to cut anything more than 8mm glossy porcelain and give it a rough faced tile and no matter how many times you scribe it won't break them properly, tried steady pressure and quick snap and it just won't do the job. Going to invest in a new set of sigmas over this year..I am converted!!
