I don't want my atty to go dry, so I check for the amount of juice left. Everytime I do this, even though I make sure it's completely plugged in....it leaks like a bugger ! I've got juice all over the battery and mouthpiece. This has happened several times. Is there a way to check the juice level without this happening ? I've sucked in raw juice a couple times...this can't be good ! HELP !
