What is a bit interesting about the prices on these rba's... I can remember not long ago people were selling these things for over $100 - $120. And now we are getting basically the same replaceable coil system for $12.50 +shipping. Im sure there are differences in bases, but geeezzz.
It's been over 24 hours now, and this thing is working great. It no longer crackles and pops, just a nice smooth burn and tons of vapor. Very consistent vape all day long. Very nice!
Wow. What rba's ??? Did you buy them? This is just the head!!!
