Stardusts are great for about 2-3 days. Then they belong in the trash can. In my experience, they cannot be resurrected. I've tried everything. But even then, it's a lot cheaper than cigs.
Eventually, something better will come along. But at this point in vaping history, I think Boge cartos are as good as it gets in terms of cost/performance. It's likely that some tank systems are better, but I have no experience with and am not interested.
