Sent in my Hercules heater to get it replaced with one that didn't steal my oil. Received a newer heater but the base has a small hole in it similar to what others have posted. I'm apprehensive to even put oil into it knowing it'll just be wasted. I think I will wait till G has found a fix to seal to the base before I run any more oil through the herc. I really want to use it, but living in a non med state makes things very expensive. I know G will make this right so I'm not worried, I just have to be patient.
