Got really good flavour from mine for about two weeks, then a disgusting burnt plastic taste ! Looked inside the barrel and unbelievably Aspire have just used a generic PLASTIC air flow insert. Mine had just bubbled and melted. Expected better from Aspire. My build was only round wire coils @ 0.75 ohms. Would suggest keep your coils as tight as poss to velocity posts, higher ohm, low wattage.
Just my experience and advise, wouldn't want you to taste what i did ! Tell you " dry hit " on burnt cotton has nothing on this !
Such a shame as i really enjoyed squonking with this RDA, great airflow n flavour. Reminisent to the classic Mose rda, one of my favourites.
