Not at all. The whole point of the Hyola Reusable Vape Kit is to keep things as simple as possible. You don’t need to replace coils, clean tanks, or do anything fiddly. There’s no liquid filling either — the pods are already sorted. You just charge the device, insert the pod, and you’re off. If you’re the kind of person who doesn’t want to mess around or deal with complicated kits, this is perfect. You vape, enjoy it, and that’s all there is to it
