I guess i had a dud...i ordered a 5 pack and have been rotating them at about the half way point before they get burned. I just ordered another Zeus....Large this time. No more coffee flavors . I did get the 10ml exotic blend sampler...a large grape and a large Vanilla to try out. They are soaking on my desk at work while the new big guy is charging. If i have any issues i will let you guys know.
