This is an outstanding RTA. The fit/finish is perfect everywhere, great threading no burrs or defects. Airflow is very generous and quiet. Wicking is very good, haven't had any problems with dry-hitting. Zero leaking, none at all. Juice capacity is very good, and comes with straight and bubble tanks. Flavor is excellent.

The only potential con is that the coil slots are only for counter-clockwise wrapped coils. You could use a clockwise coil, but you'd need to make longer legs and force them into shape. You can find plenty of counter-clockwise coils on FT, though.

I've tried a ton of RTAs, but this might be the first one to replace the OBS Engine I've been using for years.
