I have broke 3 t3 tanks in one week or so I thought I broke them. All 3 have come apart at the top inside of the metal ring! Well i am sure its got to be my juice. I vape cherry cola DIY. my wife vapes carame l candy and she has had the same T3 for about a month. So I would say do not put cherry cola in a T3. Why can't these companies make tanks out of different material? Bums me out. I have been vaping for a little over a year and finally found something that works rather well and now if I want to use them I have to change favorite juice. I am tired of cartos.
