I have the mini, and it’s absolutely perfect for my needs, which is generally small things like letters, etc. I prefer doing cakes with gumpaste flowers, that’s my specialty, so I don’t see myself using the machine for large decorations.
(I just posted a few photos of a cake I made using my a few different shapes from the CRICUT machine)

I didn’t have ANY clue how to use my machine, but my sister is a scrapbooker, and she helped me learn how to use itl!! I have found that certain small fonts don’t work as well as others, but in general, as long as I don’t have to write on any of my cakes, I’m happy with my machine!!
feel free to message me if you have any questions!! ~~ cindy
