Ok - been using my defender for a couple days now and the turbo cartos and I've gotta say, I'm loving it! It took me a little bit to get used to it, only because I've only used auto
batteries, and it took me a bit to get used to the manual button. I charged my battery last night, and I've been puffing away all day on the same battery - before I'd be on my third by now. So that is awesome. The vapor and flavor are much better as well, so overall, I'm loving my defender. I did have to modify the cone to get it to fit, I just took a big flat head screw driver and twisted it in the narrow end of the cone to widen it a bit, and the
threads were tight at first, but that had also loosened up after swapping cartos a couple of times.
