Ok mystery solved after talking to yocan forever and the place I bought it.. neither of which were much help. The thor only works with flat top 18350s not button tops like vapes.com sent me.
Just a heads up to those of you who have received pm's that Yocan has a new pen coming out soon and has been contacting members regarding reviewing them. I know a few of you have wondered whether this is legit or not.
Remember.... this is not an invitation for members to contact them or post here regarding getting a review unit to beta or review. Our rules clearly state that is a no no.
