Example Input: I am only drinking it, so it won't be wasted, and I have to rotate it with a Coffee People product, so I remember why I like coffee.  It is really wan. The strongest flavor profile is tin.  I love creme caramel and am a huge WP fan, but the flavor strenth and consistancy of this coffee does not impress. Choose another - you won't be sorry you did.
Example Output: 1

Example Input: Several of the seller's listings indicate 20% Kona blend.....but the delivered product does NOT have this package printing. As a long-time Kona coffee drinker, the contents are more indicative of 10% (or less) Kona coffee. Have ordered twice....and completely disappointed.
Example Output: 2

Example Input: I am a  big fan of carbonated soft drinks and juice drinks. So while I strongly disliked the Switch Black Cherry flavor, I wanted to keep an open mind to Switch Kiwi Berry. While I started off with an open mind, after drinking most of the can I wished I kept a closed mouth. I found the carbonation level to be satisfactory, but I felt the so-called Kiwi Berry flavor could be summed up in one very technical term -- Yuck! Not only was the flavor bad going down, it left a lingering unpleasant aftertaste. Further, the 8.3 fl oz drink is high in total carbs (34g), sugar (33g) and calories (135). My overall opinion of this product is the same as it was for the Black Cherry variety -- i.e., it is not worth drinking even for free (as I did thanks to the Vine program). If these observations don't turn you off, drink up and enjoy!
