its possible that the order may have been filled incorrectly. it can happen. human beings work there hehe. but send a message to IMYOURSALT (his name is Ty) and let him know what happened. im sure he can take care of you.
on the other hand, since you have an eGo, and this carto is made for the eGo, then why not just use them? take the free upgrade! only difference is the size, you cant use the cone (which makes things simpler), and you get more
juice capacity.
