Imeo, First off, thanks again for the iatty, it is special, you need to make more of them.
I tested the nextel wicks by first handling them over a smooth dark surface. The particle's off the wick accumulate very quickly, and they are significant and surprising.
After using the wick in the iatty for 24 hours I drained the fluid into a bottle, set it aside and refilled with fresh liquid. The used liquid is full of the nextel particles and they are visible to the eye.
I tryed using a filter in the iatty drip tip to filter the vapor. It filled with liquid very quickly, within a couple draws it gets clogged. So the liquid definitely is getting to the lungs.
I went back to the original wick. My cough, and shortness of breath went away.
I liked the nextel performance, but I wont use it. Since I am using the iatty, I can use whatever suits me.
Furthermore on the clogged wick subject.
Recently I returned to using my UFS with a quality 3.5 ohm atty, it showed signs of clogging within 24 hours. So it isn't necessarily a iatty issue. For me it is the ability to disassemble the iatty that allows me to inspect it, repair it, thus making me more aware.
All "other" atomizers are not capable of this, therefore they are used until they are used up.
