I bought poppin and boom and have used both in some dishes. They smell great and they taste heavenly! I'm honestly surprised, pleasantly so. Boom is especially pleasant--it's being marketed as an umami seasoning and that's exactly what it is. It amped up an already tasty mushroom dish through the roof!
The only thing I think could use improvement is that there isn't any shaker lid. That would have been a little more convenient.
