If I could've given this product 10 stars, I would have. It is the best thing I've bought for my scrapping/cardmaking. Ever.
It has so many useful features, with the main one being able to cut up to 12x24. It allows you to expand your crafting to making your own scalloped paper and lace cardstock (with the help of Design Studio).
If I'm not using Design Studio, I love being able to move the blade to start cutting exactly where I want it to cut. And then there's cutting in portrait mode, fitting to the page, fitting to the length of the mat (for the larger mats), and being able to cut multiples of the same item all at once.
And then there's the multicut feature. With this feature, you can cut slightly thicker cardstocks, like Bazzill Bling, and even thin chipboard. I have cut thin chipboard, think the thickness of two or three cereal boxes, in my Cricut on multicut 4x.
There is so much to say about this product, and it's all positive, glowing praise. The Cricut Expression is by far the best investment I have made for my scrapbooking/cardmaking hobby.
