You ain't been here all along? Bro!welcome!
You'll love the brassy! I love mine and can't believe how it keeps punching even when the battery level drops way off! Today, I was happily vaping away on my brass CC and couldn't remember when I changed the battery, so I pulled it and checked it and it was at 3.5! With the aluminum, I notice a decrease as soon as it drops below 3.7.
It never occurred to me that you did not already have one!
