I have ordered. Ordered a 6 pack. After 10 days, and no shipping confirmation, I contacted them and witin 24 hours they had emailed me a tracking number. I got my order 4 days later. They sent me a 12 pack to make up for the late shipping. The flaver was good. Reminded me of a mix of red bull and grape soda. I drank one at work at about 2 in the afternoon, and determined that that was a HUGE mistake. They do actually work, and pretty well. It just sucks because I have yet to find it in a store.
