Just got a hold of a bottle of Valgous brand Grape Escape 15ml. 65pg/35vg, 6mg nicotine and has a nice deep flavor to it. Says it's artificially and naturally flavored, tastes more natural than some of the grape/fruit flavors I've had before. From my understanding this is just a rebranded version of Dr. K, which I've used in the past, specifically their american tobacco, menthol and blackberry flavors, with blackberry being the favorite of the 3 I've tried. This juice comes in a nice glass bottle with a squeeze dripper which I prefer over the plastic bottles that have to be squeezed. All in all a good choice and just shy of $5 which is a bit less than what I've paid for the Haus brand I got (awful).
Figured too that I'd mention the Haus brand I got. Now mind you, the flavors I've got are watermelon (bought twice) and currently cherry. The watermelon flavor was decent, but it definitely tasted like pure artificial flavoring. My one gripe about it is that it's pure pg juice, no vg at all or very very little. On their own site it states that it's got pg, but doesn't mention vg. I've seen others mention that in their own reviews/comments, but Haus themselves has replied saying that it's a 50/50 ratio despite their ingredient list saying otherwise. I got very little vape from this cherry flavor even though the watermelon flavor got ok vape at best, but the cherry vape production was equivalent to the amount of smoke you'd get from a lite cigarette, or maybe even a lower brand cigalike. With it being $5 + change for a 10ml bottle, I was better off with Valgous' 15ml bottle for nearly the same price. My advice is to just stay away from Haus brand .
Edit:
There's something I've always forgot to do and that's to steep my juices. I usually just get 1 bottle of juice at a time, so of course i start vaping it right away and wouldn't shake or steep it. My guess is with the Dr. K / Valgous brands is that they need to be steeped. I think the flavor was just settling to the bottom and I would get it all in the first few fills of my tank and any fill after that was just vg/pg with no flavoring. I just picked up a couple more bottles today of Valgous' Cotton Candy and Energy Drink flavors. I shook the hell out of them for a good while and took the caps off, put them in a dark room-temperature place and imma let them sit there for a day or so to see if that helps the flavors. If so then I'll know for sure it's not vape tongue and that it's just they needed steeping.
