So for Christmas this year my lovely fiancée is getting me a Kato Hammer clone as my first mechanical mod. My question is about the safety (or lack there of if applicable) of a Efest 800 Mah 1830 button top in the afore mentioned mechanical mod. Ideally I would like to run a .7-1.0 ohm set up on this device with a kayfun clone. (Rocket) So please enlighten me and help me stay safe with my new Hammer
