I just tried a build in it, dual 24g at about 50 watts. I got the wires secured, but they drop out easily - you've got to hold the dead end of the wire to adjust the coils. If you cut the dead end off before you're happy, it's all over. That's on the clone, mind you - which has also messed with the vertical position that the legs terminate at, meaning the vertical height of the coil is restricted. 5 wraps was the most I could use.
When it works, it's nice, really flavorful. But the airflow just doesn't work for dual coils. At all. I might try a single to give this thing a fair shake, but at the moment I'm thinking that form came before function. It's a shame, because it's a BEAUTIFUL looking RDA. They outdid themselves in that department.
