Depends some on what ohm coil your using. The lower the ohm 1.8 or less you get a faster hotter vape and you drain your battery faster. You use a 2.4 ohm coil it takes a bit longer to get to that hot stage and with the more resistance your battery last a bit longer. I agree my T3 beats my protank but I like the glass of the protanks to hold my menthols and its handy that they both use the same heads.
I build my coils between 2.4 and 2.8 ohms cause I like the cooler vape and having the battery last through my workday.
The only evods I've worked with are the ones from fasttech and they work OK once I put my own coil build into them, but I got tired of constantly refilling them.
I also purchased a couple Vapeonly BCC's and what a piece of crap it is. Before I even got out of the startgate I had to replace the mangled coil it came with to notice that the head was pressfitted in and not screw in, got mediocre vape quality, on my first less than half tank it began to gurgle then flood and after sitting overnight it leaked badly. I emptied it, cleaned it out and put back in the box and will never use that piece of crap again. I have to throw it away cause I won't sell such a substandard piece if crap to my worst enemy.
I feel better now that I've ranted.
