I myself have just started last week with my first ego c twist an I have a couple tanks now in one is Red hots yummy. An the other is Halo Torgue55 tobacco flavor however it's a 15ml bottle only been vaping it since this past Friday an I already am starting not to like it. It was real good in the vape shop I've now filled my tank 3 times with it. An starting to get yucky. An the actual vapor from it my partner complains it smells bad. So what to do. She's never complained before with any of the other tobacco types I was using pen style before with tobacco flvrs an a cola flvr. But my actual first flvr I've got real tired of is vanilla. An watermelon. Those from the pen style. Hoping to find a good juice now with the melon flvr it will be much better I think coming from a tank.
