OK, I had the holder clip UP not DOWN. But now I'm messed with it so long my mats are not sticky so they can't hold the fabric. So frustrating. I was so excited about this and after 48 hours (could have finished a quilt) I have not made one cut.
I'm also irked every video shows the pen and cut holders but now I have to buy a pen and holder -- another 20+ on top of the 399.
With all that I will say the computer part is very easy to use.
