I don't know if I'd want that in a water bottle, since most high quality ones will maintain temperature for a long time. That said, I love my Ember "smart" coffee mug which keep coffee hot despite being open air. At the same time, I don't use any of the smart features. You can tweak things via Bluetooth, but I just keep it in default mode (ditto for my Oral-B iO9 toothbrush) |
