Wow :( I was hoping the Persei would be the one I could settle on. Can't deal with these cartridges...
I don't see a price on your website about the Hercules because it is sold out with that extended backorder slapped on the back. And is there a link you can provide that has more information on...
Hi my Persei unit just all of a sudden stopped heating up. Recharged the batteries, and tried it both on my single and double tops. The button comes up blue and stays blue but I am not getting any heat or vapor. what could be the issue?
