wellll... I finally did it... curiosity got the best of me and I purchased the TFV4...
well built, heavy, solid, easy to take apart, easy to fill
starting off with the 3 coil head ( .25ohms) with the airflow control at 1/3 open, drip tip control closed...
loaded it up with Legend.
very intense flavor, decient vapor production ( 50W) but at 36nic... whoaa.. no lung hitting on this one at that nic level...
Im gonna give it a few days and see if it may become my favorite...
only issue so far, replacement coils are running about 5$ each.... ohh and BTW the unit came with a RTA "deck"... single coil design. Might be able to squeeze a dual into it but space is limited...
