i am using one of the new clear ones from hoosier on my epower. it's okay. i am leaning towards it being a bad apple. i have two more duals to try...the 1.5 and 1.25 metal cartomizers. havent given up on the clear one...yet lol these are my first cartos on my epower (been dripping and using turbine). i was using the njoy rn 4081 and i liked the cartos on there alot. so i will hold my judgement until i use the metal ones on my epower. but i am definitely loving the dripping! great flavor and great vapor with a good bit of TH considering i am using 50/50 blend. will probably go back to 70/30 blend though...i want that TH back. keep us posted on how its going with the epower! i might be ordering one for an acquaintance soon.
