Keeps my coffee perfect - Cauldryn Fyre Mobile Water Bottle

When I first saw this I was drawn to the boiling feature to make water safe when I hike, and it does a great job of boiling water, but I find myself using the lower temperatures more. I can set the lowest temperature and that keeps my coffee Perfect for me all morning. I have to charge it once or twice a week. I have used it to cook freeze dried food too. I haven't brewed with it yet, but I am sure that will work just as well as the other functions. The battery is a little heavier than I expected, but it packs a lot of juice! I've even been able to charge my tablet once in a pinch. That was after using it all morning to keep my coffee hot.
