Does a 24mm tank hang over your current mod? On my Wismec DNA200 it sits almost flush with the control face of my mod. I will try to take a pic with the TFV8 vs the TFV4 if you'd like a comparison.
I have this and for fogging a place up, this tank is hard to beat. Don't expect longevity out of your juice.
I think flavor is far better out of the TFV4 than TFV8. but even with the TF-t8 coils the TFV8 makes far more cloud but not as dense.
No I have the uwell 2 on ATM and its fine. Was thinking of getting the wismec RX 200 next month as well . but all this tpd stuff going on is making me think I should wait cuz I mite not need a powerful mod if we only going to be allowed 2ml tanks.
