    So far I’ve only used it with a pnp coil and wasn’t that impressed. It is a tight fit in a Rev.4c BB and coil would not read. Popped it into a Cthulhu and worked fine. Finished the coil, removed boro and the back was covered in juice. Could possibly be user error/sloppy refilling. will give another go with different coil in a BB before trying Rba bridge.

    + PROS: Airflow options w/inserts from slightly restricted DL to MTL Pnp coil adapter Price
    - CONS: Tight fit in Rev .4 Possible contact issues when used in BBV Possible leaky seals

    Just received the Cthulu 520 tank and I am really enjoying the rebuildable part. The airflow (3.0 airflow pin) and flavor are excellent. I am surely going to try the pnp and nautilus adaptors soon, but I prefer using my own coils. One caveat about VaporDNA-I ordered the 520 as a birthday gift to myself and noted that on my order. I received gifts from VaporDNA in my shipping package, with a written note, and I want to say thank you. It was a joyful surprise.

    + PROS: It is awesome for MTL, and even Better for DL
    - CONS: Finding the right coil placement is key for flavor.
