What a trip lol. I was wondering when they'd come up with something like this. Not quite what I was curious about, more like a multiflavor tank that could be rotated or something similar to the old multicolor/cartridge pens with like 3-4 colors to vape one at a time. That way there'd be variety on the go without having to wash out a tank and rewick/refill with a different flavor. This seems like it's a step in that direction. Might be a good way for diy'ers to sort out flavor combinations without mixing up a combined batch, keeping flavors separate.
The only thing that concerns me with any type of over the top or one of a kind innovation, they tend to run into problems. If nothing else when it comes to replacement items, boring generic designs are usually more compatible with a variety of things like o-rings. It looks like the big bear has some sort of silicone seal that runs up the sides to separate the halves of the tank. Hopefully replacements will be available. Unlike my bachelor tank from them where only some things are replaceable, other seals like the silicone seal at the top around the fill ports there's nothing available. Replacement part kits only include a few of the other seals and screws.
