I started out using a KR808D-1 auto battery, and have recently switched to a manual. I heard good things about manuals, but I'm not really sure I'm into it just yet. Curious to know how exactly to get the best vape from the manual? Do I press the button as soon as I want to vape like on the auto? Or do I press it ahead of time and wait a few seconds? I seem to just hold the button while I vape, but also heard that some release and then press again. Just not sure what the best method is on it for making me a manual believer. Thanks!
