Just picked this little beauty up from my local B&M. SS construction, 5 ml capacity, top fill. And best of all it uses the kanger OCC coils. A brief Google search found this tank to be under $20. So far I'm loving it. 2 tankfuls of 80/20 juice later on the .14 ohm ni200 coil. Thing has airflow galore and flavor is great. No leaks and top fill works flawlessly. I think we have another winner here at a budget price.
