Know how blueberries don't really have that strong of a smell? It's for a good reason, especially once you sniff the blueberry case. Insanely sweet smelling, the case suddenly turns tarty and attacks your nostrils with a smell you're pretty sure the dictionary has no word for. Many were reminded of Welch's snacks, while one person who gave it a rating of zero said, "It smells like a wet nursery. Yuck."
