The mobile Alert 1 device has given me more confidence in getting around and feeling more secure. It stays around my neck during the day but on the charger by my bed at night. I pay extra attention when getting up during the night to make sure it is around my neck before walking. My physician was very glad to see that I have purchased this especially when I am getting up during the night. He explained that this is the time people might have more chances for a fall because they are not as alert I have unintentionally set the alarm off two times and your representatives were very kind about this when they answered my calls so efficiently. Of course, I hope I will never have to use it but it is a comfort to know you are there if I do.
