Ted it shouldnt be flavourless..
I would actually liken the flavour factor to the DSE901, and most certainly better than the Dura/Titan/510
I take it you have got
through the primer? as I found the primer quite yucky, and being a Penstyle which I havent used before it took some getting
through.
Are you getting any vapour?
If not, try pushing the atomiser down gently, hear it click, and then using the cart gently twist it clockwise. This tightens it a bit.
I found the black atomiser that comes with it, hard to tighten as its matt black and fits tightly so that final screw in motion can mean the cart twists while the atomiser stays put..
I have now changed to a Silver throw away and its better... for me at least...lol
