Taste is okay.  Not blown away.  Hidden is the fact that this is truly a decaffeinated coffee.  Only place to find this out is on the bottom of the box.  Not what I want first thing in the morning.

I have been buying ONE Coconut Water with a Splash of Pineapple regularly for awhile now. I like the flavor and ordering it on line is very convenient. Also, I have had no problems with delivery.  Unfortunately, IPROZON has just lost my business.  I didn't mind paying $15.00 for a case of 12.  I will not, however, pay $39.95 for a case of 12.  That is robbery.  I can walk into Fred Meyer Grocery and buy a case of 12 for $17.88.  Plus there are other sites still selling it for $15.00 per case.  I noticed IPROZON is still selling the other flavors of ONE coconut water for $15.00 for a case of 12.  So what on earth are they thinking.  I am quite unhappy with having to trust one of these other sites with my credit card information, but I am willing to do that versus paying nearly $40 for a case of 12.  Quite ridiculous.

This is a really easy way to make terrible iced tea.  Sometimes convenience outweighs taste, but not always.  What this product doesn't tell you before you buy it is that the ingredients are: black tea with tea extract, hibiscus and citric acid.  It's not just tea.  And it doesn't taste like just tea, either.  It tastes like powdered iced tea from a jar.  It has an overtaste of lemon -- that's probably the citric acid.  And that fake tea flavor that comes from powdered iced tea mix.  I'll probably drink it when it's really convenient.  But I won't serve it to friends!  And I won't drink it if I have time to make a glass of real tea and pour it over ice.
