Ex Input:
Of the few Hot Cocoa flavors we've tried, this is the best so far.  It has the richest flavor and I dont notice the artificial taste that others have commented on.  Its also very affordable compared to other k-cups right now.  I thought that the k-cup making process must have gotten more expensive over the last year, but now I know they are truely sticking it to us since these are still reasonable priced.

I decided to try this although I am not a big fan of flavored waters.  It is quite refreshing and the flavors are quite vibrant and not weak as in some concoctions.  I happen to like both coconut and pineapple so there is no problem with the basic idea and both can be distinguished in the mix.  The one drawback for some is because pineapple is a rather strong addition, even a splash puts it up front and center.  This added to the coconut may make it far too sweet for some.  It would certainly be a good pick me up after a workout or, in my case, after shoeveling the snow that seems to be deposited regularly this winter in the Northeast.
