ha just jimbo i have been vapping for about 2 and a half mouths now the last two weeks has been with the gogo and i have enjoyed them a lot with the gogo.i started off on carts then on to the cart,o and the clear,s than on to the
tank,s and i was never happy with any of it.i was on the great hunt when i found this web site then i found were folks were talking about the gogo and started to read all of the info on them as i still do waiting to see if all of the fussing start to get them to work but no i just top them off charge the batterys and enjoy the day.and i did order a 2nd kit.and you can leave the carts sit a day or two and it will be ok if you can put the thing down
