Dat Money Doe, Stay Gold
The Trickster drip tops by Double Helix Designs are custom-poured acrylic, medium-airflow tops that are designed to work flawlessly on a number of popular RDAs, including the following:
Petri (use biggest o-ring. place on tank and pop last bit of o-ring into RDA)
Tugboat & Patriot V2
Lochabar by Dominus mods
Glacier by Vaperz cloud
Pi2 (build small)
The subtly-contoured design makes these ideally comfortable to use, while maintaining a large amount of airflow compared to stock 510 drip tips. If you are curious whether these will work on your RDA, give us a shout and we can make sure before you purchase.
