The Capstone rda is a versatile rda the ability to use vertical or horizontal coils is a plus. Unfortunately because everything is crowded you can not use a very big build because the barrel is to close. I recommend using the included glass cap so there’s more room and with the glass cap it provides better flavor. It’s not a bad rda and i understand the thinking behind it but it just falls short. It’s definitely worth the price and it is a easy build rda. Definitely a better squonk than dripper. Eciggity has the best pricing on this rda so you should have one in your collection.
