I bought this 1 week ago today. Yesterday the battery kept heating super hot like it was going to explode without using it for a good 2 hours. Then I hit it and it hit really hard but not like it should maybe 2 times. Then awhile later felt like it was going to explode then quit working.
If your device is very hot, please STOP to vape.
And unscrew all parts, turn off by 5 clicks the power button.
