Setting this up was a breeze and after figuring out a system and rhythm, making the buttons comes easy. Yes the base does rock when making it but that's only if you're cranking the handle down hard and fast (don't do that). Make sure you're good about separating the plastic films because they do get stuck and if you try and put more than one in the machine then it will mess up the button. I bought these to use in my art class and my kids LOVE it!
