I recently purchased an ss 4nine clone from 101 vape and the mod looks sleek, sits flush on my dark horse, and hits like a beast but I've had some issues with the mod. First of all, Battery rattle. I installed the firing button in the correct way but I'm still getting some major battery rattle. Secondly, when I fire my mod it tends to get hot on certain spots of the mod. (Really hot) anyone have tips ?
