As the heating core, mesh plays an important role. Each tiny structure change matters. Just like a tailor-made suit that should fit perfectly on you, the mesh for the Profile 1.5 was tried and tested again and again to get the best result. All changes were aiming at the same target, flavor production.
Please note that the new mesh is not interchangeable with the original Profile RDA mesh in that it’s 1.4 times the area of the original one.
