These are a throw back for me. First time I had one was back on my first deployment. I eat them pretty regularly now when I see them on sale. Flavor is great; I would just rather have a bar with whey protein instead.
These don't completely fill you up. But if you're looking for something that will tide you over for a bit until you can actually get a meal, then they're perfect. Good flavor and a good burst of energy when I need it.
