I've been periodically playing around with some 400 grade mesh for months, started some time last year & tried it in a few different atties, just to get a grip on the whole story. I've had varying degrees of success & it always seemed to get the better of me. People talk about mesh wick with such affection so i wasn't going to just give up but it has still taken this long. Now i have it in 2 rda's inside a micro coil & yup, i might have finally sussed it. Simple enough but when you're fumbling around without any direct help it can still present a problem. Maybe all the trial & error downtime is the learning curve i needed, the benefit of knowing what doesn't work before getting it right. A cotton cloud as a liquid retainer & a mesh straw in the micro coil makes a flavoursome vape, it's like bike riding without stabilisers. Ready for the leap into genesis now !
