Ive read for days now but theres so much different info. I bought the ego twist 900 mah VV battery, with some kanger carts. What Id really like is a ceramic cart With no polyfil and no tube in the middle to possibly melt. Something that works well for thick oils. Usually I smoke shatter and occasional wax. I also would like to find something that works ok for hash or a hash/bho combo. Something for herbs would probably vape hash too. Its not fullmelt. Ive been looking at gentlemans vape carts and heard delta9 are better but similar. Want to know if they are worth the price over Kangers, if they'll work better for my purposes. Also which ohms to get/voltage? does it matter. I have trouble with this. Thanks to any FCers who can help.
