ive used rubis all my life the only one i have not used is the new rubi sigma type cutter.
i bought a genesis 600 cutter and to be honest it cuts better than any cutter i have ever used,although it cuts better than anything else thats where the quality ends.
the build quality is poor,the gauge is useless the rubber mat falls off within a day or so,the cutting tools are real crap(you can use rubi bits which fit perfect),the snaping system works loose and flops really quickly so you have to keep tightening the screw,then its to bloody tight,the box clips are crap,the rubber stops on the bottom to stop it scratching surfaces fall off all the time.
now after that little slagging i still think they are the best breaker ive ever used even with porce.
i only tried this cutter as i was getting so ****ed off with my ts50+ and tr60s and i got the genesis dirt cheap,and ive yet to find anything it wont cut it also cuts thin strips fairly well ie 15mm off 400x400 good quality porcenot that you should have to do this ie:i had done a kitchen then the punter decides to have the hall done as well,so the set out was all to ****.
genesis need to do there homework on build quality,but rubi need to look at there breaking quality.
my next buy will probably be a sigma 700 or if the reports are good enough i might try the new sigma copy cutter as its a lot cheaper i think,so if it breaks as good as sigma i may go for that,just waiting on more opinions.
