So I had my new device come in today, an eleaf iStick 100w. I put one of the button top efest 18650 batteries I got along with my order only to have it push the positive contact up inside the device. I was very disappointed. I was able to get the contact back out and I removed the button tops from the batteries. I'm overjoyed at this point. I put my fishbone rda from icloudcig on top of the device, rocking a 1.2 ohm dual coil build. I set the device to 20 watts, the maximum of my previous device. Vapes great! So, I figure it's time to crank this thing up to 50 watts and see what I've been missing out on. Things look good, wicks are wet, battery is charged. I bring the device up to my mouth and take a draw, only to have my build burst into flames lol. I accidentally took up smoking again as I inhaled the smoke coming off it. I started coughing my .... off as I brought it away from my face and extinguished the flames with one of the coughs. I got rid of the build and cleaned things up, at the moment I'm vaping at 30 watts and having a good time. I'm not sure if it was a hot spot or in general a bad build because the cotton should have been adequately juiced. All I know is, I'll never forget the first time I vaped at 50 watts.
