Yep indeed, using different devices can really swap up how flavours happen. What's more how you set up your airflow on an RDA or RDTA can too. Wick length can be a factor, thickness as well, material.
Let me see you got:
wattage
temperature control
wire type
wire shape
wick length
wick thickness
wick material
air flow too much
air flow not enough
barometric pressure
atmospheric pressure
wind velocity
wind direction
indoors or outdoors
temperature
time of day
, ... and on
I can list at least sixteen different variables a person might need to consider regarding vaping flavours, there's plenty more. I could be all day running down a complete list and all night again into the next day. People though expect other people to know every intricacy, or off kilter variable to know how to achieve this or that. It isn't enough to tell people vaping is highly subjective, what you find works well for you is your possible best and you'll only find it by trial and error, a pinch of luck. Nah, nobody wants to read/hear that or accept it. Somebody has to know what is best. Well, let them go find the Jaun named Somebody and take their advice, I say. I cannot help them any more than I'm able and if they don't listen then what point to help at all? And that's not being an asshole, or prick, anything negative.
It is admitting the reality of vaping. And I think, imho that reality is a very liberating one. Because there are no big corporations pushing an image of vaping, pushing flavours, pushing this or that gear. No, there isn't really a "push" like with cigarettes. Because the companies in the vaping industry realize we live in the information age and information desires its own freedom, and will be free. That means anyone that buys brand Echs juice and finds it unpleasant will post a negative view of brand Echs, anyone to millions of anyone-s will see that. How can brand Echs ensure they minimize bad reviews? Well, maybe up their quality, quality control, maybe have beta testers? Even then there's still no guarantees and Brand Echs realizes this just as it customers do. All anyone may do is to do their own best in life, then, it is up to hoping for the best results. If you find difficultly in accepting that you may as well go dig your own grave, crawl in and die. There's no way to help you further. This not only applies to vaping but anything in life really.
