Hi LowThudd -
I vape mega 808 autos, one of them I got from V4L and then I got two more from GoodProphets. The V4L one has no logo on it, none of them do. I love them. They take a long time to charge and I wish they'd last even longer than they do, but they vape very well. Having three of them though, I usually have one charged. A while back I got a PT and that fills in just fine when needed. I just this week sent for a GreenWorld G400 auto 2-piece which seems like a super-mega 808 batt from the way it's described. That's the first different PV for me since starting out with 808s - I've just been very pleased with them and with cartos. I see zero reason to deal with attys and dripping.
I also use nothing but V4L VG cartos with my 808s (VG milk chocolate), so that in itself says how much I like them. I use V4L's VG milk chocolate juice with them too, cut down from 36mg to between 6-10 mgs with Capella flavoring (dark chocolate + a drop or two of super sweet). I just don't want to vape anything else, I really like it.
So that's a big "yes" on both the mega 808 batts and the V4L VG cartos. But YMMV (your mileage may vary).
My thought is that the G400 and the new E2 ceramic XL 808 cartos with it might be similar to what I have going now only better - better being lasting longer between batt charges and carto refills. If so, I'll have all that I'm looking for in a PV. All the E2 suppliers I know of happen to be sold out right now and China orders won't be processed until after their holiday, but I intend to try them as soon as more are available somewhere. Meanwhile, I ordered some mega 808 cartos to try with the G400 (and the 808 mega batts or course).
