Mickstar - glad you posted this!
I've been using BWB juices for 7 months and absolutely LOVE them. By far my favorite juice vendor and has gotten me through the many months before Bloog started offering juices. I've ordered tons of juice from them in the past but my last "good" batch was dated 4/12 and 4/13 (30ml bottles of Backo, eJoker, and RY4). Since then I've ordered Vanilla Bean (10ml), Coconut (10ml), Wafle (10ml), Honey Flue (10ml), and Adirondak (15ml) all on 6/21 and NONE of them work in any cartomizer, clearomizer, ego-T, etc. that I've tried. I also have 3 30ml bottles of Hunter's Blend, Applewood, and Casablanca all dated 7/9 that a friend gave me when he was frustrated they didn't work in his cartomizers.
I've been searching for ANY PV, atty, or carto that'll work with the "new" BWB because I love the flavors so much. I've tried G4 clearomizers, top coil cartomizers, Boge 510 LR and standard cartos, ego-T attys, etc. and ALL of them work for the first 5-10 puffs and then go burnt. Once burnt, nothing can save them and they have to be chucked. I've thrown away so much random crap it's not even funny trying to get this stuff to work. All of it worked with another 70/30 blend juice vendor that I tried first to make sure it wasn't the device but then die a horrible death by the BWB juices.
The whole thing has been very frustrating because I have yet to find another juice vendor that I really love the taste of - I've found a few that are good but none that are on par with BWB. I really hope BWB fixes their issue but I'm very hesitant to try again with the amount of money I've sunk into the quest. I blamed the v2 Bloog cartos at first since the timing was about right but even the old cartos I have died and then all the other devices I tried fell to it as well. Definitely a BWB problem in my opinion after a LOT of testing.
Here's hoping the problem is fixed! If anyone else has luck please post the born on date on the juice!
