Personally, I feel that it is more of 'quantity' problem. My guess is they have about 50 million parts and widgets for 50,000 different PV's and so many dollars to spread around to buy replacements when they run out of them. Then they are at the mercy of overseas suppliers for a lot of those items and have to wait til they arrive stateside, and are at the mercy of stateside manufacturers and suppliers for most of the rest they don't assemble/fabricate themselves. So I don't blame them. Do we want them to have 3 different PV's, 5 different cartos & attys, and 4 different batteries?...............you get the picture. They want us to have the biggest variety and newest toys available. My advice is to order a lot to stock up when they get your stuff in house, enough to last 90 days or so, then get more when it comes back in. Which is simple if you can afford it. I agree, those Mega DCC's are addicting, too bad they don't make one model for most 510's, or one that fits most Mod's, instead of trying to jury rig some adapters that don't look/fit right. I'd stick with MadVapes, they seem to adapt quite well to problems, they'll figure it out for us as time goes on. Now that Chinese New Years is over, inventory problems should start improving, I read here earlier. And you're not rambling, just expressing your thoughts..........
