Promising review: "I didn't think it was possible to feel this way about a rolling pin! I make a LOT of cookies. And the most annoying part of it, to me, is baking my cookies and finding that they're different thicknesses, or slanted. This solves that problem. Just roll out your dough with the thickness ring of your choice on either end, and that's it. If you're used to using a traditional rolling pin (like me) you may find that there's a tiny learning curve when it comes to using one like this. But I promise, it's not difficult once you get used to it. I could see the thickness rings getting in the way if you plan to roll out a large circle of dough, say for pie or pizza crust. But if your primary usage is for rolling out sugar cookie dough, go for it. It will change your life." —Angela
