Just got my replacement battery in the mail, since my first one was DOA. It came fully charged for me, so I popped it in the box mod and fired it up. Was using a carto at first, but it was giving me a slightly burning taste, so I figured I would top it off and try again later. I switched to a regular atty for dripping for now. My first drag must have been it burning off all the old caked on juice because it was extra nasty. After a couple of dry burns, I dripped enough to make sure the atty wasn't dry, and vaped away. I think I'll like 5v, I feel like I get more TH out of my low nicotine liquid, and a ton more vapor. Thanks to Ken at boxmods.net, fast shipping and excellent customer service.
