Query: Smelly

I do not know what has changed in Carex items, but OMG please change it back. These back wraps smell like bad seaweed. Can't even use them. I purchased one, and after gagging from the smell, I emailed the Carex company directly. They promptly got back to me, and even sent me a replacement free of charge. Unfortunately, it smells just as bad. I have another Bed Buddy product, the original cold/hot pack (long and white with two blue ropes on each end) and that smells yummy, like rice almost. But these back ones are not the same materiel inside or out. Horrible.
