I got the survival kit about a year ago, and still use the rda regularly. My only issue was with the nautilus x coils, you're stuck with 1.8 ohms. Ignoring the nautilus part, it's an awesome rda/rta kit.
As with all top deck RTAs it can be a bit problematic with wicking in cold weather and with high VG, but leaving the wick loose ish and with a small gap between the deck and tank, it wicks just fine.
You don't get any spare hex screws! That's something that was a right pain, the screw heads go bald and you don't get spares.
Other than those things, it's a banging kit.
