I have no Idea what four roses single barrel is, send me a link I would be happy to check it out Mike,
Also, Another reason WHY I recommend the 510 is because in a way it IS a DSE or RN
JUST redesigned and it is made MUCH MUCH better, also there are options for it like the PCC.
When I say that it is redesigned to be better, it is very similar to the DSE or RN in ATTY design
But the Gasket the is in the atty of the 520 ATTY is much better at keeping it from leaking out onto the batt.
Also take a look inside the 510 Batt, you will see that there is also a gasket in there to protect it from liquid getting inside that can kill the Batt.
Take a look and confirm it for me please.
So in conclusion, the 510 is better just because it is designed better because it is made from knowing the flaws of other e-cigs. I hope that makes sense.
Happy vaping to ALL! to you to Mike!
