@soozyg, I had a long talk with the FiLIP people on the Telefonica booth. They have many discussions about the possibility of letting the child remove the watch.
The current model does allow to be removed, but it is as diffcult as opening a medicine bottle, you need to use two fingers to unlock it and then move the lock upwards.
I can understand parents want to have their children "monitored", and this product has some good features. But there has to be some common sense about the amount of control.
I remember a discussion a few years ago with a mother of a 6 y/o at my children's school in Madrid. She wanted her son to take a cell phone to the school annual field trip. The school has rules that so not allow that, and parents should communicate only with the teachers, to allow the children to interact and spend the time learning and playing.
But this mother was so upset that she didn't want her son to go on the trip if she couldn't call him everyday.
Unfortunately I see this type of devices becoming more and more popular.
