Are we going to go through this argument again? As of right now, I think the consensus is that Klasse has not changed. The consensus is also that CarLack of Germany makes the Klasse products (well, they package their CarLack product, or something very close to it, for Klasse), and that Carlack has a new version of "AIO", which is being imported as Jeffs Prime. I think the consensus is also that Jett is an improved version of "SG". Were they reformulated for VOC compliance? Who knows and no one is telling, and I am so sick of this argument I don't care. Since Klasse is still selling, I'm going to presume that they are compliant. Will they ever be improved? It doesn't seem likely, since CarLack seems to have aligned itself with Jeffs to market the new products. Of course, that doesn't mean that Klasse may not be available forever in its current formulation, and it does seem to be at a better price point.
