[EX Q]: I've been drinking these for years. When they changed the formula, it ADDED SUGAR, tastes WORSE, AND often LEAKS. Totally unacceptable, especially for how expensive these are. I've called Gevalia numerous times to try and explain why then need to go back. Seems EVERYONE liked the old formula better. And it was healthier for you. FAIL!
[EX A]: negative

[EX Q]: These were not "large" pearls. Just regular size beads and regular length necklace, not 48 inches, which was disappointing because I specifically needed larger beads. Total misrepresentation of the actual product I received.
[EX A]: negative

[EX Q]: While the duvet insert would have been absolutely perfect, size, fluffiness, and soft. It came with two huge yellow and black spots on it. Since it comes vacuum sealed there's not good way to return so I'm bleaching it in hopes it'll come out. Just disappointed that it looks like I got a returned one.
[EX A]:
negative
