People go on and on about V1 as if it's the be all end all custard, and it's really not... it just has a shed load of Diacetyl in it, making it quite a blunt instrument in some ways. After 6 months vaping it, it began to make me feel queasy, so I switched, with some trepidation, to v2... and was astonished to find I FAR preferred it. It's not as rich or heavy as v1, but that can be a good thing. It's much more subtle and delicate, but still tastes velvety and delicious, with an identical vanilla note, light on egg, and more like vanilla pudding than actual custard, just like v1 is. No off notes or butyric taste even at 8%. I would call it a must have, but I recently tried FA Custard Premium, and it's absolutely awesome - try that or INW Custard first, then circle back to this one.
