Hi guys , my riva 510 arrived this morning and it's on charge as we speak . I'm following the instructions and giving it a 8 hour charge . But what I want to know is if you guys fill the cartridges or drip straight on to the atomiser . And if you do that later then does this reduce the atomisers life span ? I've got 15 blank cartridges and A drip tip so I can easily drip onto the atomiser. Also how do you clean your atomisers ?
