The one thing that smok used to do that was extremely exceptional and I feel they did better than most everyone else was putting out versions of tanks that actually came with an rba. Some of my favorite rebuildables are actually older model smok atomizers that came with an RBA or because the products were older I could purchase them and an RBA for a relatively inexpensive price. At this point a lot of people in the United States are not going to purchase a product unless it uses a coil that they already have a lot of or it has a rebuildable option so that it's future-proof. And nobody really releases rba's with their tanks anymore. The biggest issue is when you find a tank on sale on a site ten to one that same site isn't going to have the RBA so now instead of having to buy both separately and pay for one shipping you're having to buy both separately and pay $20 for shipping which makes it not worth getting it all. If smok would return to putting rba's in certain editions of their tanks I would go back to buying smok products
