Started out with the Flex 6 and recently upgraded to Flex 9 because the food portions are just right. Seriously, the hardest part about eating healthy is not really the cost, it's getting the portion size just right and I have to say that after eating a Freshly meal, I'm never hungry. I love the different choices of healthy carbs, and the food doesn't taste too salty or spicy, but just right. I really like the steak with green beans, and am starting to experiment with different things I wish they would add an easy option to upgrade; as it stands, I had to cancel my Flex 6 and the add the Flex 9, but there should be something to click on when you want to upgrade to make it easy.
