Ok, I posted this somewhere else as well, but anywho! My 510 is two days new. Straight off the charger it was awesome!! Next day, gross taste and BURNING and I mean burning my throat! Could it be the primer? Thinking that the atomizer was dry, I dropped 2 drops on the atty and then topped off my cart. Same scenerio. Burn burn. This sucks. Guess I'll puff it for a week or more without inhaling to see if it gets better. Any other suggestions at this point? My blu is tasting better minute after minute...and that just ain't right.
