This is a very nice RDA. I've been using the included BF pin on a Therion and it has been performing very well. Airflow is surprisingly quiet and incredibly smooth, and flavour is good too. Easily one of the best RDAs i have tried.

In my opinion this is a good atomizer for small to medium sized builds and not so much for big air and giant clouds. The second cap might provide enough air for power hungry builds but that is not so much my preferred kind of vape.

The machining seems good - even when trying to look for flaws i can only really say that certain edges aren't perfectly smooth to the touch, but everything fits nicely together and works as it should.

I can easily recommend this to most vapers.
