@pancser thought I would revive this thread.
For me the v 1.5 is a big improvement over the original Beserker. Looks have improved a bit and so has usability. I couldn't get on with the original and couldn't be arsed to faff about with it to hit the sweet spot. Wicking is much, much easier, although I did stuff the wick channels on my first attempt and got dry hits. Since then I have not had a dry hit, leak or gurgle, even after filling the tank with the airflow left open. You do get a slight bit of residue when resealing top cap though.
The airflow ring is a bit on the tight side, but not really a problem. It's better than being too loose. You have an airflow slot under the coil, similar to KF Prime, which to me is no bad thing. You can get a really tight draw out of this, and yes
@John R , I mean toiger toight. Fully open the airflow is a moderate MTL. If you're looking for loose MTL, look away now.
Flavour is subjective, but I would compare it to a KF Prime that is working well, meaning it is very good.
Overall, I prefer it to the True and Hastur Mini, but that is personal to me. It is 24mm diameter though, so will put off
