I've tried the Caramel Tobacco, Robacco, and Belgian Waffle, VG, 32 mg, extra flavor. Flavor-wise, I think they're quite good. The Caramel Tobacco is a pretty artful combination, and the Belgian Waffle is more than just maple and butter. I sometimes get a hint of grain alcohol in the taste, maybe because they thin the VG with ethanol.
After vaping them for a while I came to find the tobaccos a little harsh, but that could be because they're 32 mg or extra flavor. Previously I had been at the 16 to 24 mg range, and now I've dialed in at 18 mg, so getting into the 30s is definitely too high for me. It might also be that Tobacco Absolute doesn't agree with me. These days I mostly use them in mixes.
One thing that had me a little worried was that they billed me as Wagner's Country Gifts, possibly because they didn't accept MC at the time. Googling that name, I found an Etsy store that sold soaps, candles and lotions. It briefly crossed my mind that they might be using non-food grade (scent?) flavoring in their liquids, but I'm guessing they aren't idiots. WCG doesn't have anything for sale anymore, so if that was them, it looks like they aren't active in that business anymore.
Anyway, I've also purchased nicotine and other supplies from them. Very fair prices, and based on their DIY offerings it looks like they know what they're doing.
