Example Input: This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix.  However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink.  ;)
Example Output: 3

Example Input: I saw this product on Oprah and wanted to try it, I was impressed that it was vegetarian and lower fat then mayo. I thought it would make good "BLT's", but without the real beacon. It was just OK for me. The product does come as described and tastes OK, but something about it just tasted too fake and I didn't like the texture. It's not real creamy lake mayo, or even low-cal mayo. I like low-cal fry sauce a lot better. I have to say though, it's just a taste thing, and someone else might love it. I still use it on burgers, (mixed with light mayo), but no one in my family really cares for it that much. I wasn't happy that with free shipping it took a month before it was even sent out, that seemed a little ridiculous. The packaging was good. I like that the jars are plastic and not glass. However, I would not purchase again or recommend, because the flavor is just OK.

Example Input: I have a sweet tooth and so does my three year old son. This is a great after dinner dessert that I feel good about giving him and myself. They ARE healthy and you CAN taste the flax seed in them, but I have really grown to love that healthy taste and texture. I even come to crave it now. They are satisfying and filling and my whole family loves them. I buy them in bulk and love other Hodgson Mill products as well.    If you eat nothing but white flour products and can't get used to or absolutly hate whole grains and their taste and texture, then this is not the product for you. If you are the family that tries to make healthy choices and have healthier alternitives then this is a wonderful product. I still love to have my junk food (Pillsbury and Hershey's here I come!!!) I just try to have it only on very special occasions. The rest of the time I choose to nurish my body and satisfy my taste buds. That is when I reach for this brownie mix.    My only complaint is that they don't taste too great after only a couple days. So make up a batch, eat em' up quick (within 2 days) and you will be smiling!
