Hey there, purchased at smok Xbox BT50 two days ago on your website. Got it today, cool. Set up in the menu, wattage, how I wanted the lights, puff count, etc. Worked for like 2 minutes and now will not fire. Cant figure it out. Im old school, use a carto 1.7. Had the wattage at 7-7.5 as I have had on my other box mods. Nothing. Dont know if this matters, but it doesn't read the voltage. Any ideas or should I send it back?
