I'm not ready to give up on the 510 yet (only been using it 2 days), but I've come to the conclusion that a STEADY, good throat hit is a "must have" for me. It's non-negotiable. So far, the 510 is not doing it for me. It's far better using the drip method then filling carts, but it's still not good enough. Maybe it's the atomizer? I dunno. Anyway, how good is the throat hit with the VK? And is it consistent? I'm new to the world of e-cigs, so I'm not familiar with what would be natural limitations vs. product faultiness, if that makes sense? I don't like the fact that I get decent throat hit for the first 3-5 hits, but then it's hit or miss after that unless I drip more or top off. Is that a common issue for all e-cigs, or is this an atomizer problem, or is it a common 510 problem?
