so the hammer top will work with the EO carts too? also anyone know when the hammer heating rod will be back in stock with it? are there alternative sites to purchasing the hammer top since the w9tech site has like 10$ shipping fee total including the handling part. How does the core work for the ophos, omicron lite, minicron? arent they just the battery with the heater? how does that work. can the ophos, omicron lite, minicron work with the hercules sr74x with the core? or will it only work with the persei top/ the 8 top. can the core be used with the "
MINICRON LITE OIL VAPORIZER" at 7.4v with the sr74x?
