D watch arrived pronto, and watch had to be set up with some difficulty for an elderly person but instructions are clear, if you follow it slowly. watch sits nicely on wrist, seems to be large for a watch but John got used to it quickly. It has a nice feature that you can contact the watch via the phone. difficulty will be to explain to the wearer how to handle the phone that gets activated by the alarm button. The alarm button speaks for itself and can be remembered fairly easily. I am now struggling with the geofences but hope to get advice from this excellent company. It is a relief to follow John while he is on his bike and know where I can find him if he gets stuck. all in all a good geolocater and phone in one. the price is high but the quality is good.
