Our smart bottle can track how much water a user drink every day and use the length of the LED light strip to reveal the volume of water consumption.
Each adult should drink 67oz (2000ml) water every day. We designed the bottle volume is 500ml. So, people need to drink above 4 bottles that can meet the standards. When they finish 500ml, the stripe will light one LED. All of the light will light when people drink 4 bottles at least.
