Been pretty pleased with the Artery Nugget 200W Pod (
SKU 9725409). Have a 510 adaptor and found an RBA coil that works pretty well!
Listed here at about the same price but I was able to get mine on sale a couple of months ago for around $20 bucks!
Have had the original (single 21700) Jackaroo and piers is right...it's a tank!
