Quality at budget price
Bought very cheap. This is the third eleaf tank I have using GS air coils. All work perfectly and none cost over £10. I have had no leak issues whatsoever and the coils seem to last at least a month if not longer. I'm not a sub ohm cloud chaser so these tanks are perfect for my needs. Not sure how well they handle sub ohm you would need to ask someone else..all in all though, great priced value for money tanks from a reputable supplier.
