Let me give you an example: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
The answer to this example can be: 5
Here is why: The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.

OK. solve this:
I have a slightly different version of this - different brand. My son started using it around six months, and he really enjoys it. He DOES get messy if he eats something sticky or juicy like banana or watermelon, but whatever... Anyway, I also had trouble cleaning it, until I tried scrubbing it with a nail or vegetable brush. That works pretty well. It takes some time, but not as much as it would take to run food through a food mill or blender, or cut it up, then clean it up off him, the chair, the floor, the dog, me, well you get the picture.
