Maybe I went overboard, , I have 10 devices with different flavors in each to keep things fresh. It works for me.

I have 8 mods going at all times .. each with a different flavor.
Four at one end of the house, and 4 at the other end, and I travel between the them all day long.
I only fill them with 2-3ml at a time, as I like to switch flavors each time I refill.
I DIY, so I have dozens of different flavors to choose from, and I have them made up a good month ahead of myself....well steeped.
