Fight the cost of factory coils and be able to adapt to your own liking
Compared to many other RBAs, this is easy to build and wick and it comes with a 510 adapter so you can check your ohms, dry fire and wick your RBA on either a standard mod or on your 510 based ohms tester that has a fire function. With current conditions with shipping bans and other restrictions you should get rebuildables as factory coils won't always be available and this is easy to build even for those with sight and agility problems.
