I got the Martelli set for half price last year and never used it much, but I started a little project where I had to trim a layer cake, starch, press and then cut into pieces. I noticed that the Martelli doesn't grip the fabric like an Olfa...the fabric just skids on this mat more. Ironing scared the snot out of me. After about 15 layer cake squares I noticed a foul odor. It turned out to be the board under the ironing surface. It got so hot I couldn't touch it. It smells foul because it's just pegboard. I had to stop and let it cool down to finish the pressing. The next day it still smelled. I boxed it up and there it will stay. Also the surface is warped (yes it was stored flat) and that causes the cutting and pressing mats to start slipping off the rotating part. Definitely not a happy camper, but I'm glad I didn't pay the full price.
