NO NO NOfirst time I have heard this and I resisted for so long and did finally buy one. waiting for my rba to come now (bought several OHM's brand) so I am just using it with the coil it came with and that was my first question "how do I get more air) I was told with door off you get more air and you do but the reason I bought the thing was so I could have one refined looking thing to take out in public and not look like an idiot amongst those that do not vape (Miniken with an aromamizer look scares my bridge club ladies-JK) NO NO NO, I resisted for so long because I did not want to buy one more thing that did not do it for me. I am so sad to hear you say this and if only it had come a few weeks earlier...……...
You may like the RBA just fine- I just rebuilt my Dot AIO RBA with a 1.2 micro coil and it seems little better with the air flow. I had a .5 clapton in there before- the micro coil vapes better. Very restricted lung hit- I wish the air flow hole was one big one instead of these 4 little holes. Would have been really nice if they had come out with a DL RBA. I have Dot's after market panels on and the air flow channel should have been cut larger, plus your hand can cover up the air slot a bit.
Hey and it doesn't leak which is always a good thing!
I have mine on the 3rd power setting- at least the flavor is pretty good.
I do not vape with nic any more-
It is a beautiful little device, I bought mine for the same reason as you- nice to have some of these AIOs to take out and about with you- no tanks and mod system to have to drag around. I only buy rebuildables too. So at least this has an RBA, I will never have to worry about buying factory coils for it.
