I get the juice under my rda with almost all my mods, regardless of brand. Just a compatibility thing. Some squonk pins work better with certain 510s. I installed a small o ring on the base of my squonk RDAs to stop this from happening.I just opened mine up too, been using it since it first came out, and NO signs of leaking inside.
I've gotten a little juice under my rda if using an atty with a short 510, but not enough that it leaks or makes a mess. I don't even see it until I remove the rda.
@BillW50 It's worth getting it replaced under warranty. You already paid for it, why not?
