This is a good product, specifically, for someone like me with dietary restrictions (i.e. lactose intolerant, diabetic, etc.).  While very pricey, it ends up being more cost effective than off-the-shelf alternatives. So far, I've made light ice creams (milk alternative & sugar free) as fruit sorbets. The recipes that are available are fairly simple and I like that, of the recipes Ninja has, they have provided the measurements for alternative ingredients (i.e. coconut cream instead for heavy cream, stevia for sugar, etc.). The one drawback is that there aren't many recipes (although they seem to be adding them). Overall, it's a solid product that I would recommend, particularly, to those who have dietary restrictions.
