From 7 years back the DID20 genny tank stainless tank . They worked excellent the taste was wonderful and the 400 and or 500 mesh stainless wicks handrolled, angle cut on bottom of wick gave more surface area to wick the -e-liquid. Can attest back then 90% pg 10% vg DIY never a burnt hit vaping till almost empty. Did season wick on top of stove. Nowadays have moved on from these but they work and do not leak at all even with the thin e-liquid i still today use.
Revisited them couple years back and will say MTL inhale is very very restricted only wish back then the draw was adjustable , also coupled with the cleanest taste experienced from these still holds true for moi.
Below example of wick being fitted to tank and not yet seasoned.Also mm vapors came out with stainless post and nuts little later which i have used as well.
Was not a cheaply priced tank but these were well made this example was with a clear plastic type tank for lack of better words and also available a stainless tank forget if they came with both but have some of each and would not ever sell them. Remember when there were co-ops i was in one and one of the lucky ones that did not get ripped off in that co-op and have 12x12 sheets of 500 mesh stashed !
