well my sigma's come, cracking service it came next day, so I've had 2 days to have a play and first impressions are very good it feels a solid cutter , bit different to the rubi but straight forward to use ,the job ive been on is an on going job and the tiles are not the easiest to cut but the sigma did perform very well slightly better than the rubi ,the only negatives I have so far is the plastic insert on the handle does have a little bit of play and I did have to give the sliding setter a bit of a tweak as it wouldn't travel over the bed ,
