Is the locatable watch used by the elderly really useful?

The same result * * * expenditure. My children also have positioning watches, but they didn't bring them when they went to kindergarten.

One day, his father put it on him. As a result, when I came back from school, I found that the watch in my child's hand was missing. I asked the teacher, and the teacher said it had been put away.

Positioning watches usually have a short battery standby time and need to be recharged almost every day. Actually, I feel limited in use. What's the use of positioning or talking if there is no electricity?

Kindergarten children, if they accidentally let their watches fall into the water and break them, the teacher can't say clearly. From this perspective, kindergarten teachers are definitely reluctant to let children wear this watch.

I don't think this problem is actually a problem. I won't wear it if the teacher won't let me. I will send my children to the teacher every day and pick them up after school. What's the use of positioning? It is even more inappropriate to make a phone call. Kindergarten is full of activities, so keep quiet in class. What is the gap between children and you?
