Got the Super Mini as a gift loved it because of the no leak factor and the no bubbleup top refill.
It just didn't hold as much juice as I needed at work. So did some test marketing... fancy words for wasted money on other brands. Finally the Black 25 mil. became available here and same results....no leaks no bubbleup and a really honest 5mil. tank. Some say it's basic? Pfffft! Mandatory is more like it.
Just wish Tobeco made a seal kit and spare glass globes.
