I have one a really like it. I think the difference in version 1&2 isin 2the drawer underneath has a catch to keep it shut. And 2has a lightly frosted cover over the lite.
I've cut 2 heavy cardstock sheets at one time before, mostly by accident, but it works just fine. I've even cut some chipboard with it. Fairly thick, I just needed it cut and it was there, so I tried it.
Blade is supposed to get better over time. I had read that when you first get it to take a piece of paper and make like 40 cuts on it. It does make it flow,cut better.
