Nice offer but I have to pass got the new any 260 on order. To answer your questions battery life is good on a kayfun but I'm a dripper and like over 30w so it last me about 10 hours chain Vaping. Has temp control for ni200 and regular watts for kanthal. Only screen glitches happen for a split second rarely but never stay like my other boards. I'm building a vapor flask clone housing with a dna40. That's why I'm trading it.
