I don't see the TFV4 in VE's online shop today, but they do stock the TFV4 Mini. You may face issues if your coil resistance is too low; the Subox mini can't handle it. 50W of power may not be enough for you as well. Dual claptons or a 3/4/6 coil occ usually requires more power.

If you are still referring to the TFV4, it is a tank for intermediate vapers, not beginners. However if you have a bit of patience, you can learn to wick it right...it just takes some practice.
Wick it wrong and it will leak away happily.
Get a unit with extra-burry internal threads on the base section, the deck's o-ring will be chewed up and it will leak.
If the air pressure goes from 1014hPa to 998hPa in under a minute, it will leak. (I'm serious.)

The TFV4 is a medium between getting lots of clouds and some decent flavor. If flavor is your priority, then you'll want the TFR2 dual coil RBA to go with it. However IMO you'll get better flavor with cooler vape and longer battery life on a kayfun or mini goblin.

However if you DIY juices, the TFV4 can be very handy. If your juice tastes good on the TFV4 with single/dual coil, you know it'll taste very good in most tanks, and taste excellent in drippers/"flavor" tanks. I have 3 of them.
