So my previous setup was an mvp 2.0 with an aspire nautilus bvc 1.8 coils. I wanted an upgrade as the 11 watts were no longer doing it for me anymore. So i purchased the new rdna 40, and put the same nautilus and using the same juice on it. But im vaping at 9 watts. It seems the device gives me a hot vape, 9 seems perfect, 10 -15 is hot, 16 and above is unbearable with a burnt taste. And this all depends on how frequent i vape. My question is, is this normal? Is something wrong with my rdna 40? Kinda bummed out cause my intentions were to have access to higher watts, but i am vaping at lower watts than i had with my mvp2.
