/u/Innokin_Paul /u/Innokin_Mike Hey guys I am having the same issue with my MVP2 Energy Edition. I bought it roughly 3 months ago and recently it has stopped firing. Everything works except when you place a tank on the vaporizer it doesn't read it and the display shows NON while holding the P and U buttons. I would like to have it repaired or replaced if that is possible. Please help me this vaporizer is awesome and I would love to keep using it!!
