BTW Pete Busardo reviewed sigelei Kaos recently, and it's their 2nd latest board (latest is duo-3) and it still has the same TC mode issue, if you keep pressing the button doing multiple vapes, the temp just goes higher and higher.. exactly like the 213. I don't see how the snow wolf will be any different.. they have had, what, 2 years now to fix it? I don't noticed it in my sigelei stuff as i only have a puff every minute or 30 seconds when i'm actually vaping, but still...
