Good starter RTA

I really like the quality of the materials used as well as the look. Super simple build deck that anyone getting into rebuildables. Smooth draw and decent flavor.

Use more cotton!

I've been having a rocking time with this little guy. Great flavor, but this thing will flood if you don't have a good amount of cotton. Do not thin, and cut longer than you think you'd need. Also if you're not getting tight airflow, I recommend tightening the bottom 5-10 pin.

Awesome flavor, not tight enough MTL.

It is great flavor, really awesome, but the draw is too loose for a legit MTL, I find the Berserker MTL to have a more legit MTL draw, but this one beats it in flavor. Drip tip is too loose as well, and get plenty of condensation and a lot of liquid comes up through the drip tip.
