pfaber11, the main reason that folks in the know are against e-lites is because there are so much better & cheaper alternatives available.
As for vapourlites, even if they are compatible with e-lites, they are also overpriced.
And again they so over exaggerate what their cartos are the equivalent to -
"Each Tobacco cartomizer is the equivalent of up to 40 standard cigarettes, approximately 200 cigarettes in every one of our 5 packs. You should only use Vapourlites branded cartomizers with Vapourlites batteries and accessories."
Sigh! the sooner this sort of misleading advertising is stamped out the better IMHO.
