Got 12 of these now, I don't think there's much between these and the HG2's which I also use in my mechs n mod's.

Nice and clean out the box, finished well, smooth threads, Very good short 5ml tank, coils last well, RBA works great(with dual SS Clapton 0.33ohm 65w/Hard, mounted on a Smok R150)I prefer it to the Minos25 that came with the R150 because it's shorter and doesn't seep a drop. Well recommended.

Good authentic Smok TFV4 coils, my preferred coil for ma TFV4, almost half the price I can buy them at home

A bit of a disappointment for me, supplied coil lasted two days and was a bit bland flavour wise, Full on flavour and clouds with the RBA'S but it leaks from the bottom regardless of air open/closed when filling and has dropped the lot all over my Lux while unattended, I've tried different wicking options but have failed to fix the problem so far, runnin out of interest now

I've owned 2 of these (Black/Silver) for a couple of months and they have been very good in both flavour and vapour production. It is nice and short and sits nicely on my Alien, fits in a pocket and has not leaked, holds 5ml of my current favourite, has lots of airflow if required and the coils last well, both 0.25 and 0.3ohm. I run the RBA with dual SS claptons 0.33ohm 65w,the Tornado 150 is as good if not better than the Smok Minos,(which I also own 2 of)because there's no fiddling with the bottom of the tank to adjust juice flow as well as air flow IMO. Given the price point Tornado 150 is 100% recommended,Honestly it's a No Brainer I've now bought 4 in total as one has been misappropriated by a mate. Is there a better review than that? Borrowed by a friend?
