I don't mind posting them publicly

I am hardly the only person who knows.
One is, the balanced charging board is supposed to not work well. You can't prove it by me, I never charge batteries in the mod anyway. I have, and use, stand alone chargers. But if you're intending to charge in the mod, maybe the RX is not your first choice.
The other is the 510 connector is kinda janky. If the 510 connector on your topper is too long-- I have read longer than 4.6mm, but I can't swear to it-- the mod will "lose" the atomizer occasionally. It will show zero resistance and not fire, despite the atty being plainly visible right there on top of it, or the fact it worked just fine 5 minutes ago when you set it down after your last vape. I do not claim to understand this, myself. I have an Indulgence MT-- the evil black one, #3-- that will do it a dozen times a day. But the same mod will only do it once a week with MT #1, and hasn't yet done it in over a month with MT #2. All three tanks are supposedly interchangeable parts, except for the fact #3 is painted black and the other two are stainless. Anyway, it's not hard to fix. Just take the tank off the machine and put it back on; it will magically find it again and vape just fine until the next time. Not a real problem, but it can be annoying. If the annoyance factor bothers you, the 510 can be easily replaced by a handy person with a drill and a soldering iron and 7 bucks to buy a new connector from Fat Daddy Vapes or Varitube.
