Okay now i have received my testing units as well. As for the big ego atomizer I think its a misunderstanding that you should put as many drops in there as possible - let me explain why;
Once you fill in say 8 drops - then you vape and its all good. But you will have pauses, where you dont vape. In those pauses the existing liquid will seep down, and either be out of reach from the heat, or will seep out if there is a minor leak.
What i think is good about this big ego atomizer is when you drip in 4 drops - then you vape. Then you drip another 4 and keep on. However - unlike any other atomizer, the mesh in this will try to "hold" the 4 drops ( because of its big size ) and this means those 4 drops do NOT disappear so fast. So the time between dripping 4 drops becomes bigger and bigger, since it always is using some of the previous 4 drops you dripped in there.
I dont know if this makes sense, but the reality of it when using it this way is that you can keep this going for a looong time, and all of it tastes very good. And since it has a "reserve" in there, it never goes bad instantly, it just mellows out in the taste, and you know thats your queue to drip more. But the cool thing is that you can then wait for longer than you would on any other atomizer, since it has that reserve.
So - in short: I think this atomizer works best with 4-6 drops at a time, since to me it uses those drops 100% - if you drip more than this, you are constantly wasting drops. And, even when dripping this "moderate" amount, i feel compared to my 801s (of different variety) that i get more vape, for a longer period of time.
Phew.. let me know if youre confused. I know I am
