The commercials are a bit corny*, but I'm a huge fan. The fact that their half-gallons are still half-gallons, and not 1.75, or even 1.5 quarts like some of the other jokers really appeals to me. Even if it is more expensive per ounce, and they don't have as many flavor options. The Homemade Vanilla flavor is excellent.
*I was going to link a commercial on YouTube, but it was too terrible. And I've linked Kinoki Foot Pad commercials, so that's saying a lot.
