Not sure whether I posted in this thread already. We had a vendor with a Tobeco V5 clone for €22 here in Spain, so I simply couldn't resist obviously. I also got the M2L Kit. (I am a very "extreme" M2L vaper and like my airflow very tight).
The Tobeco is a totally solid device, machining etc. is all top-notch. I cannot even imagine how an authentic could be better. YET, it doesn't solve the main issue that I think the V5 is a very "meh" (at best) device for M2L vapers, even with the kit.
SM thought they built something amazingly great with the V5, this may well be, but definitely not for M2L vapers. I just dug out one of my ancient KFL2+ spares and built another KFL2+, it's ridiculous how I can get the perfect airflow with the tiny screw in 2 seconds, something I never managed with the V3 or the V5. If you wick the KF2L+ right, it is still the king of MTL, there are flavour notes I cannot taste with the V5. (Someone explained this with the larger chamber of the V5 which is suboptimal for MTL, so even the KIT doesn't make the V5 an "excellent" MTL atty. The V3 however is "ok", I just wish tank would be even bigger than the 3.5ml of my "Plus". (But I also had to mod the V3 for tighter airflow)
** Gimme a V3 with a HUGE tank, larger deck, the "improved" isolator which doesn't turn like mine..and I think it would be perfect

I still hope that SM with their next iterations comes to their senses again and thinks about M2L vapers.
