I built 2 different boxes thinking it was my box that was making temp mode not work on my first box so I put everything into the new box and mounded it with the bolts ... So now the temp on screen goes up like before and still no vape .... I'm out of ideas... I tried different rda rta tanks pre built nickel coils and nothing still shows temp protected on screen once it his target temp but nothing... And help would be great I'm about to give up or throw this thing across the room ... Lol just messing ha ha I wouldn't do that..
