Well first of all I will tell you to make sure you clean it well before first use, lots of machine oil throughout and a few metal shavings in the chimney area, but cleaned out easily. The airflow is great for an rta and it makes nice clouds. The flavor is very good also. It was a little awkward to build on the first time, but after a few failed (shorted out one coil, and messed up a couple figuring it out) I finally found a great set up, dual 24g 2.0mm 6wraps .18ohms, it was easy. This set up gave me plenty of room around the coils for airflow and enough space to prevent shorts. If you are on the fence about this rta, I will say go for it, you won't be disappointed! If you want to know more just ask.

I ordered mine from Trianglevape.com for a lower price than I have seen elsewhere, and they shipped it quickly.

Edit: running this on my sigelei 150 at about 35-45 (~3 volts) watts, went up to 70 watts (~4 volts) and got burnt hit, so you may want to try a diff coil on a mech mod
