Some of my carts have been refilled 4 times. So how do you know when a carto is done and you should throw it away? Does it look a certain way when you look inside them or do they vape differently somehow?
I don't want to waste 18 of these precious juice in a cart only to throw it away... =)
Thanks!
Tom
