I usually like to buy china stuff as their customer service tends to be far better than in North America. That said I think we should have a forum thread for 1) which companies deal well with reports of fires 2) Keep on teaching battery safety I charge mine in a hallway closet that I have set up as an E Station where I charge or refill my tanks or make my e liquid. I have a small fridge on top shelf for my extracts. My goal is to line the shelving area with some safety measures for charging. I have a number of eLeaf 40 watt TC mods and not once had any issues with them. The old ego twists I found caused me issues where triggers were not working right so tossed them. It would be informative to have a ecf forum thread on which battery mods have caused issues to people so we can avoid that product.
