When I buy pods, I expect that they will not last for a very long time since they are cheap and not rebuildable. The smok Nord is quite popular but it seems that their QA is bad. Geekvape Flint Kit is only a bit more expensive but has better quality. Here in our local store Shosha, we also have an exclusive pod kit called Palm Fit. It is quite cheap and a direct competitor to juul so you have to buy a pod replacement. Not so cheap if you have to pay for $40 import tax though since that's like 2 times the price of the pod.
