We have the same thing too.
For me, it was a waste of money
I ended up just baking, steaming, sauteeing everything myself and pureeing in a food processor.
The grinder is too small and makes for only a one or two meals.
I like to make a lot a head of time and freeze so I'd stay up one night and bake 6 apples in the oven with cinnamon to make apple sauce, bake butternut squash, sautee potatoes and onions, etc... etc...
I think its a brilliant invention but just not for me.
I like to add more flavor by cooking in other ways than just steaming...my baby hated steamed peas but loved when I sauteed them in a little bit of butter.
A lot of people i know use it and love it. But I'm pretty handy in the kitchen and a food processor works just the same and I think is around the same price as this thing.
