I think you are talking about the Embrace2. I have one and it's great. You wear it like a watch and it will give you the time if you touch it. Otherwise the screen stays black. You chose a few people who will be called if you have a seizure and the device is connected to your phone by Bluetooth and calls the people letting them know you need help. There's also GPS so if they don't know where you are it let's them know so if you went for a walk or something. But we haven't needed that feature since my husband is retired and if he's working in the yard he just rushes in the house.
Whatever you do put it on the wrist that you don't share bottles! False alarm and you can notify right away. Yes I did that!
I highly recommend the Embrace2. Your Neurologist will write a prescription for it and you send it directly to the company that makes them
There customer service is great. I hope it helps you as much as it has helped me during seizures.
