you are not alone on this mesh is a very difficult thing to set up. Even for a veteran it can be agrivating .
One little mistake and the whole thing taste burnt crap.
I am by no means a neewb and I am an experianced builder with genny and dripper style attys also protanks and evn I have swayed away from mesh.
What happens is you will try a hundred times to get that perfext coil set up and when you do its great ten u bump or drop your
mod the wire moves slightly and its never the same . Even if it last long enough for you to have to pull the mesh out to clean putting it back in the exact same spot is near impossable and again uour stuck fixing hot spots and sutch
I sqitched to cotton for ease of use and it works fine in horizontal and vertical setups in gennys. And there is no need to worry about hot spots .
I juzt got tired of that whole meah setup and fiddle ordeal now I just pull the old wick out dry burn the coil and stuff a new piece of cotton in ... Done
