I like it, though the qualia isn' t that strong. I got 7 capsules with 2 coffe and is not the effect most people describes. Maybe work inside and make a better brain, but that super effect of focus that most people talk about..I didn't feel it. However, If you have a hard exam, it's good for storing more data in the least amount of time and not get your brain overwhelmed. But the price is too high for it's effect in my opinion and overrated. Appreciate the intention and work.
