After having used a drip tip, I could never go back to cartridges. Better flavour and vapour production, and feeling it start to run out tells me I've finished my smoke break
As for the auto
batteries - I've yet to see an automatic battery that works well with dripping. Especially if you tend to store it vertically in a pocket or something. I suppose if you leave it horizontal all the time it might be ok. I didn't think I'd like manual
batteries when I started, but now pushing the button just happens without thinking about it, and I haven't killed a battery or had it misfire at all (one of the auto batteries I had failed in the 'on' position - it wouldn't turn off).
