RDA 101 Vape 28.5mm opinions?

[big4570]

I just ordered these as my first rda. I figured the larger size would be easier to build on. Right now my only experience with building is on a subtank mini, usually around 0.5-0.6 ohms. I'm planning on putting it on top of a 40watt regulated box mod. Has anyone used this rda, if so what are your opinions and builds?
