I have used them in the past and I would again in the future if I needed to.
However, if you are a veg*n, you will be severely limited, since it's almost all meat.
Further, it's almost all processed.
This food is not the best quality (not the worst by a long shot) and low on fruits/veggies/etc.
However, here it's something like $25 for a week's worth of food (and they mean b, l, and d) for 4. There may be some super-mamas here who can beat that at the grocery store, but for most of us, that's a great value!
We stopped using it because we didn't need to save a lot of money and I felt like the food was making us fat.
