troll rda

I was thinking about picking Up the wotofo phantom mech mod. And along with it I wanted to get the freak show, or the troll. I can't decide on one so I was wondering if people could post there opinions on the two rdas. The builds on them will be for mostly clouds. Right now on my twisted messes...

Just wondering if anyone has used these rdas, the troll, bmi Goldie, alliance v2, and the magma reborn. Wanted some opinions on them about clouds, thanks for any input!

coulnd find a thread for this, if there is please point me in the right direction. I love this RDA but lately I have been having an issue with the screws staying in place, it seems like the screws just spin and won't stay in place. Is there a way to fix this issue or do I need to get a new one...
