So one thing I have to say about the 901 that I'm sure once I empty enough cartos and refill won't be an issue, but its a lot easier to change flavors with the 901 right now. So if I'm just needing a change of pace and a new flavor, I can just put a few drops in a cart and
vape. But, like I said, once I have enough cartos with diff flavors it won't be a problem and prolly easier with the 808 since I can just unscrew and rescrew a new one.

Now I just have to work out how to tell them apart. Any suggestions?
