I have been using mine for a couple of hours with the pre fixed coil and so far it performs as well as any other small RBA I have tried. I will say that it isn't keen on too much juice in the chamber but that could be more to do with the TINY piece of wick included in the coil. It appears shorter in length than the wick you would find in say an Evod. More wicks space is available inside the chamber
Talking of tiny, the included Allen key is the smallest I have ever seen
Not the most prolific or able rebuilder I'm not especially looking forward to that
Form wise I like it. Sits nicely on an ego with a plinth. Equally as good on the Provari
No issues with using my own drip tips. Indeed they fit better than the one supplied which is a little loose on mine.
Overall for the price a good buy
One thing about the pre fixed coil it seems to have a shed load of wraps. Maybe 7 or more (its so small it's hard to be sure and I've not had it out yet). Came out at 2.8 Ohm and after some use is now 3.2! A VV unit therefore will be essential with the pre fixed though most people will be anxious to make their own with their favourite wire and wick
Finally. It has variable airflow via 3 air holes on the side. Easy to adjust. 2 holes open suits my Vaping style
