I suspect (because I have by no means tried them all) all the drippers being recommended perform well if you've got your coil & wick set up well.
And now for something a little different.
I recently got the Ice Cube. I've got a lot of juice flavors and in spite of having about 14 different atties I haven't near enough to handle all the flavors I have. I like to be able to switch juices almost from vape to vape so I was looking for something that would allow me to do that. A taster/sampler atty was what I was after as I'm too lazy to be constantly rewicking and some juice flavors just don't mix well with others. Also when trying out a new flavor the last thing I want to do is have it mix with an existing flavor.
What I ended up with was a single 'U' shaped upright coil (the coil forms a cup like structure) that I could put a small amount of cotton in that can easily be pulled out and replaced in a couple of seconds. The cotton is there, inside the coil, to hold the juice but it dosen't extend out the bottom of the coil and only out the top enough to form a nice fuzzy cotton button on top to drip onto. So the wicking dosen't actually wick from anywhere and does not extend down to the juice wells. 3 drops equals about 6 good vapes. The advantage to the Ice Cube is 1) it pulls apart easily and quickly with no threading so it's easily to open to drip/change cotton, check its dryness etc, 2) its housing is clear and you can see what's happening inside, and 3) it is painfully easy to pull apart, rinse, dry, rewick and get going again in a couple of minutes. Oh and it does produce good taste and good clouds just like the rest do.
So now I can sit and enjoy as many flavors as I want, check out steeping juice, or even revisit those I wasn't fond of to begin with, with no hassle, little effort and minimum time involved between vapes.
