I had a similar issue. finally went through 1 hour ago. I asked: 1) how many refills are in 1 cartridge. 2) how much for cartridges. 3) where would I get more. I forgot to ask the size of the solar panel. IMO the buzzbat is a waste of money. BIG TIME The buzzsol is almost a rip off. 30$ for a solar panel with a usb connection? (on ebay I can buy them for 17$) Just to support the company im invested in I would consider the survival kit. Otherwise the buzzbar alone is the only thing (perhaps) that's worth it. IMO weak product launch. Too little info. Ehhhh.... I was hoping for something bigger (and better) Cheers.
