Yeah, mine just died a slow death, but luckily still under warranty and I already filed my claim and will be mailing it back to the vendor tomorrow for a replacement. I plan on just putting a tank that I know fits on it and just using it at my desk...
Sorry to hear that, man. You think it was ver 3.10 that contributed to that?
My RX250 has been working the same as before the update; no issues. The 510's not
that bad; the only tanks I've tried that I couldn't get flush, (and eliminate all wobble), were a Kanger Toptank Mini and a Phoenix.
I recently got an iJust2 tank, (5.5ml for $13, I couldn't pass it up), and a sweet Tobeco clone of the Twisted Messes V2 RDA, ($16). They're both built very well and fit flush on the RX, with no wobble. The Melo 3 Mini does too, so any Eleaf tank is probably gtg. I can confirm that those, at least, are viable choices to use on yours when you get the replacement. I don't know if the Aromamizer Supreme and/or V2 would fit as well, but that might be the best overall choice to pair with it, (the V2 will be my next purchase).
Anyway, I did order one of those finned Kepler heatsinks, ($1.74 from Gearbest), just to reduce wear and tear to the 510, the finish around it, and hopefully eliminate this little issue altogether.
...I think I want to get an IPV5 also.
Sure, why not? They're only ~$50, ($45.99 at VapeNW), online.
