........ many have the higher ohms and still complain about it , that leaves 2 options, the tank isnt wide enough and thats been tested and the wick doesnt wick fast enough and thats where the ptb comes in and does a better job at wicking.
Bad, I have been experimenting with the wick on several of these things, not just the ones that everyone have seen here. So far, the ones that I have extended the wicks on have improved the performance. I can't tell much difference when a poor one has a full tank, but it's not difficult to tell the difference after several minutes of vaping. I'm not saying that all the ones with extended wicks work equality well, but all of them have been acceptable.
There is no doubt that one factor will be eliminated if all E2's have the same wick length. In addition, I am convinced that all E2's will be better if the wicks are long enough to touch the bottom of the base fitting. Of coarse, that would assure that the lengths would be the same. I believe this is an important factor. Until this factor is eliminated, there is no way for us to determine if this is a good wick or a bad one. As stated many times, we know that a few of these things work well out of the box. If my findings are correct, then I believe the majority of them will work well out of the box.
As for the E2's I call acceptable, the ohm rating appears to be less critical. If most of these things worked well out of the box, perhaps there would be less complaints about the resistance rating. As with all other devices in the past, all individuals must determine the rating for themselves.
About PTB. Regardless of how well it works, we are not likely to see it used in any device. Numerous makers of atomizers have known about PTB, but none of them use it in their cartridges. Most of these manufacturers are not fly by night, and you can bet that they have a good reason for not using it in their cartridges. They certainly will not use it in their atomizers.
What we do on our own is another story, and everybody has their druthers. Me included.
