PROBLEM: After reading all the great reviews, I optimistically ordered some of this tea. I've had problems with sinus congestion very often this winter and have tried all kinds of remedies with little success.  Unfortunately, this really didn't do anything for me.  The taste is OK (bearable), but it did nothing to relieve my sinus congestion.  (So far the only things I've found that have helped me somewhat are the Vicks personal warm mist humidifier and Neti Xlear)

PROBLEM: 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.

PROBLEM: I purchased this item when it was on sale.  I wasn't certain if I'd like it but I've read so much about the health benefits of green tea I wanted to try it.  This is a nice, pleasant beverage. The flavor isn't too strong.  I add a packet of Splenda to make it a bit sweeter.  The powder dissolves easily in cold water.  The flavor is natural not fake.  I was impressed enough with it that I have signed up for auto-delivery.
