The mat itself is great, although I haven't used mine for cutting - only placement. The one problem I've had is that the magnets chip very easily -- I've only had mine for a week, and already three of the magnets are badly chipped. It's easier said than done to keep them separate as they are very strong and also tend to grab on to my tweezers and other tools. I've already had one picture badly scratched from a chipped magnet. That being said, I do love being able to pick up a LO in progress to look at it before gluing anything down. And I'd LOVE one big enough for a 12x24 LO. Getting 2 mats means you have to have room on your table for 30 inches, which is excessive, and then the grids don't meet up for doing 2 page spreads anyway, which defeats the purpose of the measuring aspect and means you can't pick the whole spread up as easily.
