I just got the Revenger on Saturday and have had the Captain for a while, just ordered a couple of new skins for the Captain I need to find time to put on. Great recommendations, I like both mods too.
Thanks for always being so helpful, it is really appreciated
More than welcome 
I got my rx300 in March, absolutely zero issues (and I grab mine by the atty more than I should). No wiggle or connection problems. I use mine probably close to 75% of the time.
I’m not sure when/if they identified/fixed the 510 problem, but fwiw I’d buy another in a heartbeat.
Sorry I hijacked your thread pugs…
And thanks for the replies, I just wish it wasn’t so hard to get a straight forward answer out of the manufacturer.
I borrowed this pic from elsewhere online to illustrate the issues I was having (not the best pic) where the entire 510 connector complete with soldered wire draws out of the body of the mod.
Hey no worries at all man, its a proven and long standing issue with wismec, but I havent come across it yet personally and the 300 has been flawless for me. Thanks for the input 🖒
