I've never used any of the frozen products, but I do have a way that makes raw feeding very easy and practical.

I buy large amounts of meat and then seperate them into bags.
I portion them out correctly for each dog and write their names on each baggie. Then I put them all in the freezer.

For fruits/veggies, I made a big puree blend and then put them in cups in the freezer. When they're freezed, they are cut out of the cups and put in a large bag.

You spend 1 day doing this and then it lasts you for a long while.
