Yeah I'm goign ot be completely switching over from the penstyle IF the loongtotem works as well as Mixos says it does- I'll probably be squeexing hte liquid from the remaining cartridges fro mthe penstyle, and using it to refill the loong cartridges, I'll probably keep the Loong cartridges i nthe fridge too, just to be sure nothign spoils- probably overcautious, but oh well. I will certainly keep an ongoing thread abotu hte experience and keep everyoen informed how well or not so well it works- Got some Johnson Creek tobacco flavor juice coming too- will use that to refill the carts too. I've just got htis sneakin suspicion htough that loongtotem is goign to flubb up the order though, but hopefully not- we'll see
