Hi all, I've been coasting along for the last to months using my Halo G6 and have been very happy. Have only smoked tobacco during a trip to New Orleans when I left my charger at home. Last night I completed the Penn state survey and it brought to light a number of areas that highlighted my ignorance about e-cigs, specifically, the specifications. Halo does not offer them on their website and, while I've seen bits and pieces about milliamp hours etc. I don't know whether that's supposed to make any difference to me as a guy who just wants to vape so he doesn't smoke. Judging by the wealth of info out there, I'd need many more hours in the day to become much more comfortable with jargon, specs...everything really. One thing that has me flummoxed is the threading on the G6. Is it compatible with other carts? Also, if anyone can break down what I need to know in order to maintain the G6 for best performance, longevity etc. that'd be great. Cheers, Nxxx PS...even since posting this I've gone to a few sites and have become further bogged down in jargon..drips tips, clearomizers. I also am finding it hard to choose other e-liquids outside of Halo's due to the range. And I still don't know if I'm filling my cartos correctly & if there's a better method than simply using the eyedropper that came with my last bottle of juice.
