Almost as good as the big name brand.
4 Stars
Almost as good as the big name brand.
UPDATE: I ordered this again, but the packaging this time was pathetic. It's a good thing there's an inner seal because the cap was broken in shipment. I'll have to transfer the new crystals into the old container.---------------The ingredients are the same as the big name brand. The only differences are the slightly coarser grind and the lower price. From reading another review I found that it helps to let it sit a few seconds before stirring it into your drink. Otherwise it doesn't dissolve quite as quickly. One plus with this size and brand is the flip-open cap -- much easier and quicker than having to unscrew it and then screw it back on every time.
Thank you for your feedback
