I was just vaping away on a Griffin a few hours ago and needed to fill it up, so I closed off the juice holes, filled it up, and proceeded to vape away. After a few drags I noticed it tasted vaguely burnt so I let it sit for a while, thinking the juice needed a few more minutes to soak in. I took another hit and it was dry as the Sahara! It was then that I realized I hadn't reopened the juice holes after screwing the top back on.
