Last week I sent mine back. Mine wasn't as cold as yours (I could get light vapor, pretty sure yours couldn't get even that), but I never felt I was getting the results that everyone else was raving about. After three weeks of not knowing for sure if mine was cool or if I was just expecting too much, I sent it back to them. @WildChild all I can say is I hope you have the same experience I did. My replacement is a totally different beast. Unlike my first one where I had to preheat for 15 seconds or more to get any vapor at all, this new one needs only a couple of seconds to preheat and throws much denser vapor. My last one I had to hit it for the entire 30-45 seconds until auto shutoff every time to get hits. This new one I worry about combusting if I hold the button down for more than 10-15 seconds or so. It's nice to feel like this thing has too much power, unlike my other one that felt like it had too little. I no longer feel like I have to do everything perfectly just to get light hits. So now I'm re-learning the FF from scratch after owning one for a month But it's a much quicker learning curve with adequate power. I'm no longer just trying to get vapor from it, now I'm trying to get the best vapor from it. So glad I finally decided to swap mine up. The verdict is in: it was not producing as much heat as it should have been.
