Wondering if anyone knows who still has these now that V4L has changed their maker. Trying to avoid emailing tons of sites to ask who makes theirs. I tried the new 13 second cutoff from V4L and IMO they don't fit the cartos as well. There's a gap between the 2 as they don't screw down to the cart as far due to the threading. In fact, the last one I got only worked on 2 of 5 cartos in a box I orderd with it. It may be just that particular battery, but I never had a problem with the Kanger made ones and I think they produced better vapor. Just my opinion here, not knocking V4L or or their products at all. Just personal preference. That said, I would love a color, but black would be fine too, Just don't want white and that's all V4L has that's still Kanger.
