Why do all my other DNA250 mods only jump up and down by 0.001 ohms when using the same RDA and build in the RAW ohms? I feel like since its a 3D printed box that the ground is just not as solid as the metal boxes. Even when I vape on it it jumps from 0.20 ohms, 0.21, 0.22, 0.23 and 0.24 everytime I push the fire button. While my other 2 mods stay right at 0.20 ohms. I don't vape in TC ever and I only use kanthal a1 wire. So it should not be jumping like say SS wire.
