I have a lot of surfaces to cover, and I have been quilting for 30 years. I have had every brand except the blue one. Right now I have a Fiskars, an Olfa, a Salem (Marti Mitchell-which I like the best), and some brand that I got at the sewing expo with my 72"cutting board.
The Salem was the only one that didn't stink. The smell goes away, though not as fast as you would like.
And the only one that doesn't cut grooves is the 72". But it is made out of a harder plastic, and the rotary blade can slip, so I put the Salem on top of it. It is translucent, so I can see the lines on the big mat, too. The Salem is 36 x 24 and this is my work horse. I replaced it in Jan. after years of hard use.
You may have to try them all before you find the one you like best. My Fiskars is my second favorite. It's sturdier than my Olfa.
