fireissue

I have a puma 200w mod The mod doesn't ask if there's a new coil or an old one Although it reads the automizer So when I press the fire button it displays seconds changing but no actual fireing is happening I tried a different tank/batteries and still didn't work

KANGERTECH CUPTI buttons are jammed after I let it fall on the floor. When battery is removed I can press the buttons and they feel great. But as soon as I put the battery back inside the sticking of all 3 buttons happens. I reallY love this mod and I don't want to part with it. Has this happend...
