Well, the good news is, mine is still going fine, though as point out, it does seem like it's hitting way way harder than it's supposed to be, though after that initial pulse it seems to level out fine, but still high. It doesn't heat up either, though I've kept the wattage turned down to 10 watts on my kayfun, though it's hitting like it's probably double that at least.
On the other hand, I did just notice another problem. It looks like the battery meter is screwed. Before the update I could swear it was at around 45 percent. After the update it showed 84 percent. I wasn't really paying attention the rest of the day, paying more attention to the temp, but I do remember thinking the battery life was really good. But it just went to zero and stopped firing. Plugged it in to charge and after a minute noticed the meter was only showering one block. Pulled it off charge and it shows 84 percent again. So it looks like, at least on mine, that anything above minimum shows 84 percent while dead shows 0. Nothing in between.
I hate to say it, but this really is a huge fail. They had to test this firmware, how the hell could they not have noticed these things? It just doesn't make sense.
