Hi,
I recently bought a uWell Caliburn. I've used it about a week and I have questions about cartridge usage/maintenance etc. First, can I refill any time or should I let it get completely empty. Right now there is just a tiny bit left and it's turned somewhat solid and black. Does that mean I should clean it, just refill? Second, it came with an extra cartridge. How long should on cartridge last and when will I know that I should replace? Lastly, should I only use one eJuice per cartridge or is it ok to refill with another flavor?
