Ok, my co-worker let me use a KR808 today. Thing is super harsh and little vapor. The taste is better though. So guess I will look into the green. What I think will happen is I'll either go back to analogs or have to bulk order atomizers for my 510. Any thoughts?
I'd guess and it's just based on reading posts here esp. in the new member forum that about 90% of the people with 510's are not having the problems you are. That doesn't mean you're not having problems or that your stupid or anything. Just an observation from bring around since June.
Some of the comments about how ecigs in general are not like cigarettes and like pipes and RYO there are some things to adjust and tweak to get it down. And there are just some hardware parts that aren't entirely standarized although the 510 parts are fairly good, imo. To answer your question, you could probably go somewhere and get a bulk buy on attys and you'll be way ahead of the game even if you go through 1 a week (vs. cigarettes).
My guess is just because your asking and not dismissing ecigs altogther that you'll get it down. Whether it is with the 510 or some other model, but much like golfers changing clubs or drivers to 'improve their game' you might spend a bit more attention on getting the 510 to work for you ;-)
Blow out my mouth all new attys to get rid of the primer/shipping fluid - blow from the batt end into a paper towel until you get no more wetness. This should be sufficient to where any nasty taste is reduced considerably. Load up the cart but don't overload it. Drop 2 drops directly on the atomizer bridge and start vaping. If you're still getting some nasty taste just huff it - puff several times and don't inhale for the first session on an atty. That should really get rid of the shipping fluid taste.
After that, vape as normal but if you find yourself 'power vaping' then you will be vaping the top off the cart and then will get a harsh taste because no more juice is being vaporized. There's still juice in the cartridge but it is half way down and hasn't wicked up to the top yet. That's a direct result from hitting the ecig to hard for too long. And if you have to do that, then chances are you need a higher nic level in your juice. If you would vape it like you smoke cigarettes, you'd probably do better. Power vaping is akin to chain smoking - lighting the next one from the cherry of the last. Most people don't do that smoking ;-)
If you're not getting vapor then you're flooding the atty either by overdripping 3 or more drips on the atty that already may be too wet, or by overfilling the cart which acts as dripping since as soon as you put the cart into the atty the juice runs to the mesh or coil and floods it out.
Having a fresh batt helps on this too except it works against you if you're power vaping because fresh batts eat the juice quick.
