Example Input: I was hoping for actual juice. A kiwi and strawberry combination is one of those combinations that I usually love. In fact if you combine strawberry with anything I'm usually game (steak, chocolate, banana, etc.) and this COULD be a good drink. However, it's in the fizzy drink school of beverages and as a fizzy drink, I can't stand it.  Granted, I was never too fond of the fizzy drinks in the first place. The orange drinks were always a bad second to actual orange juice. Not that I don't love pop, but I really can't get behind a bad orange juice pop.  So at first taste, this is rather sweet. But then it goes down and its too sweet. And fizzy. The fizzy and the sweet combine and you are drinking candy. Not that pop is anything but candy, but there's candy and there's candy and this is the hard candy that your grandmother gives you to suck on to shut you up for a few hours.  Not very good.

Example Input: I got these cocoa cups based on my sister-in-law's recommendation.  It has a great flavor and is inexpensive.  Quite a good combination.  I'll be ordering more very soon.

Example Input: I have to agree that these are likely factory seconds -- one of the cans in the pack I bought was half-full and weighed only 9 ounces (including the can!). There's supposed to 15 oz of food in there, much less the weight of the can itself (full cans weigh about 17 ounces.)  If ConAgra didn't even check the weight of the cans before shipping them to Amazon, it seems to imply that they are selling lower-quality product to Amazon. The rest of the cans in the pack was fine, and I'm sure Amazon will take care of my problem with this transaction, but I definitely wouldn't recommend purchasing these unless you're willing to gamble a bit.  The ravioli itself is good - I'd agree with the other reviews, it is tasty and relatively healthy for something out of a can. I wouldn't eat it every day, but it is a nice quick lunch or snack.
