Yes, I have and it doesn't replicate good throat hit. Plus, that option would mean the OP would be limited to ONE eliquid which would not solve the over all problem. There are only about a 1000+ posts that validate the better throat hit produced with better battery PV's in comparison to small, 180 mAh PV's. It's pretty straight forward.
I would just hate to see the OP go out and spend a bunch of money on a new piece for hardware only to find that it was the e-Liquid that was the problem.
But if they are going to buy a new PV, I stand by what I say. Get a Provari. Buying a fixed 5v PV is going to Extremely limit the OP.
Where as I can use any atty/carto/juice combination by adjusting the voltage.
