No it's just sheet mesh on a roll. Depending on deck it could be length & width.
Mesh by it's very nature is a cooler vape than the equivalent resistance coil & there's no residual heat. I can run the Profile Unity as low as 45w but much lower & you'll start getting juice in the mouth as there's not enough heat to evaporate it. As for life of wicks, that'll depend a great deal on the juice & sweetners. I get a minimum of a week but average around 2 before rewicking & as long as you don't deform the mesh, a quick low power dry burn & rinse & it's good to go again.
