Here is a smart bottle that not only reminds you to stay hydrated but also self-cleans with UV sterilization. The NOERDEN LIZ bottle blinks to remind you to drink every 2 hours. It keeps your drink hot or cold for 12 to 24 hours. The bottle has a temperature indicator too.
Thanks to UV-C light, LIZ kills 99.9% of harmful viruses and bacteria. This water bottle is available in a wide variety of colors.
