The pineapple coconut combination is refreshing. I especially like that there is no added sugar. This is a welcomed change from other brands.

I used the small cup setting and even opened up the cap and scraped the excess mix out of the cup and it is still very weak tasting.

Ex Input:
I opened a can and it smelled like cigarettes which I was informed was bad bacteria.  I reported this to Amazon whom I got it from and they sent me another 6 pack for replacement BUT it also smelled badly...At this point I gave up trying. I am all for organic but this stuff was poor in my opinion.  Allot of it seemed like hard rice and it smelled like cigarettes and bad bacteria.  I wouldn't buy it again.
