I've never used flavor shots for MBV. I mostly only drip their juice. I always order Max VG, 3mg/nic (and I'll add my own nicotine as I see fit).
Also, I almost always buy in bulk, I'll place a ~100$ order every 2-4 months, and then be set for a good amount of time. When I re-order, I usually still have a fair bit on hand, so I'll let the new order sit for a bit before digging into it, so I suppose there is a SMALL amount of steeping going on there.. Other than that, I always think of MBV as a fresh-out-of-box vendor, I've never had a juice necessarily "require" steeping before it gets good. My most common purchases from MBV are a large quantity of thug juice and a larger quantity of hawk sauce. I mix 'em up as I see fit. Some days I'll kick it up with extra menthol from the thug juice, other days I vape almost straight hawk sauce (which supposedly has menthol in it already -- which I can't taste at all..)
That said, this fire cider is unvapeable. Idk if it's cinnamon or what, but I'm letting it sit for a while, hoping it mellows out. Very harsh. Very very harsh.
Also the Cheesecake from MBV is okay, but it leaves kind of a weird smell in the room. I realize it's "cheesecake" but the smell shouldn't be reminiscent of actual cheese.
