I've been using a cinnamon
juice in an evod for a few weeks now. I know I shouldn't but I figured when the tank cracks or leaks I'll get another. I just like the evod. I have a protank but have grown not to like the airy draw on it. But that isn't my point.
Over the weeks I've noticed the flavor of my cinnamon fading. Thinking maybe it might be the head, I replaced it. Still fading thought maybe it was me so I moved to a different flavor in a different tank for a day or 2. Go back to my cinnamon and first few hits are good flavor then fades away fast.
So while I'm not tasting my cinnamon much at all, I tried this new optimizer phenom from my local b&m. I thinks it's their own brand as I haven't heard or seen it before. Anyway,, it's basically an evod with a glass tank. Even used evod heads. So I filled it with fresh cinnamon from the same batch used in the evod and instant flavor. And the flavor is holding all day long.
The old evod's plastic was getting dull and turning color. I really think the cinnamon was eating away at the plastic and muting the flavor, let alone what I was
vaping. Next I need to try some of my plastic safe flavors and see how they taste. I think it will be like my coffee. I can drink my coffee in a plastic or stryofoam cup, but I love and prefer it in a glass mug. Just tastes better.
