Only thing is he didn't use it right. He did his vaping with it at 40-50J which is really way to high. Optimal resistance is .065ohms so 26awg is the best wire to use 7 wraps. 28 works well too but if you want 7 wraps you get .085ohms still works well. Only have to use 18-25J. The closer you are to .065 the more accurate it is. There are still a lot of people who like the DNA but they are 2 completely different animals. The DNA is from what I hear more accurate but the SX is a lot easier to build on. Also they have a tube that fits on the bottom you put an 18650 in it and one in the device then screw the tube into the battery cap hole. Giving you 120w in Power mode but in Joules mode it just give you more battery life. The chip is designed so that when you add the tube it automagically senses it and changes over to 120w. The DNA you have to be good with building good coils then it works fine. I wasn't.Sounds like you had a fun day Janet. Also sounds like your really enjoying the I-stick. I am using a IPV3 right now. Thing goes to 150 watts and I have never vape it above 20 watts, right now I'm vaping a Kayfun Lite V2, 1.3 ohm coil at 13 watts. Working great. I really want an SX-Mini M series. Just watched one of Busardo's review on it. Temp control got good marks. I really want to try temp control and like the looks of the SX Mini. Price and battery life are what's stopping me. $200 and it eats batteries. If it had dual batteries in series or parallel it would be different. Hopefully YiHi will sell the SX-350J chip for us hobbyists and I can build my own version.
