Does anyone know how to turn it off?? I dont want to take the batteries out because then it will lose count.

Is it easy to put money in? How about a 5-year-old child?

Is it 1.8 or 2.5 liter? Because it has 2.5 in picture and then it says 1.8 in wrighting.

Does this product have a companion app that automatically sends data to a mobile phone app server?
