I ordered a 5 bottles during the sale at 0,8,11 and two 18mg. The first one I tried was the 11mg and it tasted like cardboard. Tried the others and it was the same great taste I am hooked on. So I sent the 11mg back and am still waiting to get an 18mg replacement, plus a 5ml bottle of it to compensate for shipping cost which I thought was only fair. Hopefully it will be the correct stuff. They were prompt getting it taken care of and they called me to verify what I wanted. I read in TW's forum of the same taste happening to other ppl. Good luck guys.
