I won one in the contest and I really like it.....I gave it to my sister at the beginning of the month and she gave it back yesterday - so of course I had to check it out. 1. Nice little red button (change from blue) 2. Haven't seen the cut off affect me at all 3. The carts - I am truly amazed at the carts with this kit vs. any other kit I have ever had. Flavor not bad at all and I had one last me from 6 am to noon today and I can vape at my desk (Was pack a day smoker) Nice kit - just wanted to share.
