...I have a question about the carts and juice. I now have 2 different PVs and I am expecting my eGo to arrive in a few days. The PVs I am using come with prefilled carts. Can I drop juice on these carts? Will it ruin my atty? I am so new to vaping, less than a week and I am still trying to figure it all out. I do have a large bottle of Cloud 9 juice but dont want to screw up these PVs. Thanks to anyone with answers!
