I've never been on a diet, never tried any diet products, but when this sample came for Slim-Fast Peanut Butter Crunch Time, I thought I'd give it a try. For a "diet" snack bar, it's not so bad. Peanut butter, a little crunchy stuff covered in chocolate - how bad can it be? For 100 calories and 3.5 grams of fat, it's not bad at all. I will admit it could use a little more peanut butter and it's not as sweet as I would expect a bar like this to taste, but it's a perfectly fine snacky treat.
