I quite enjoyed the taste of Glow, albeit less than I expected. I did recieve this discovery set as a free gift with my purchase, so great value for money. And the discovery set itself is ideal for trying a flavour without locking yourself in to too many servings in the event you don't like it. My Glow Discovery set was near to expiring when I recieved it (something I knew in advance from the helpful website nutritional information), whether this had a direct impact on the strength of the cube, I'm not sure. My only critique is that it is a weak flavour.
