I absolutely like it The brain booster influences well on my alertness and memory. I feel much more clear after half an hour of taking them. I think that they even improve my critical thinking.
positive

I got two bottles for my newborn with no issue. On the third bottle, discovered a dropper that wasn't built into the cap. Not sure if it's a defective batch or what. (Which means you'd have to wash the dropper every time... not ideal at all.) I submitted for a return/replacement and the fourth bottle I got had the same issue. If this is just a new design, I'll definitely have to just switch brands. :(
negative

I followed the size chart and it was way too small. Useless. I don't even think the next size up would be adequate. Terrible product information. Sized for teens not adults?
negative
