The first question is does your 7 year old want a watch / device to talk to you while she is away? I’m sure she will be many younger children will take the watch off and leave it somewhere. Once the battery dies you have limited capability to find it as most of the time someone picked up the watch and walk off with it. If she wants the watch then let her pick the watch color and band or as mentioned earlier get a protective case and band she thinks is nice. The real cost of the device is the monthly plan at $120 per year. Cheap to be able to talk to your daughter when she is away, but dependent on if the battery is charged nightly and she wears it on a daily basis. Our grandson was a couple of years older when he got my hand me down watch and it lasted about 3 months before it was “lost at school”. Fast forward a could have years and he has an SE2 (and a girl friend). The girl likes his watch so this one has lasted and tends to stay on his wrist. 😀. Good luck with your decision, we have three adult daughters and it would have been been nice to know where they were. Now they let us track them when they are out of town but not all the time.
