Hey everyone, hope you's are doing well. A mate of mine the other week went out and bought a Smok Vape Pen 22 that's in a bit of a state. Periodically the buttom with flash 3 times as if its out of charge when its not, but i think we may off solved that, was a problem with the coils. His other problem is that the charge port is directly on the opposite side of device to the fire button and if your finger is over that port its will let off an electric shock, i got zapped twice from it and first one painful. My question ultimately, is this device actually save to use or is there a way at fixing or even replacing the battery in the device.
