We were looking for an emergency telephone for my father. Since most "real" emergency telephones are equipped with a transmitter that works only on the landline, they are of course useless if the senior is still so mobile that it still can leave the house. In this case, there is this phone !! The device has a top-quality, easy to use, equipped with red emergency button on the back and a few other features, such as flashlight, organizer, etc., this phone is highly recommended. In an emergency, the cell phone sends (by the way free for all networks) not only an emergency call to the previously entered telephone numbers, but also sends an emergency SMS to any mobile phone = very practical and useful because you do not always home is. The device is small, but still good to grip and to very easily. We have attached the mobile phone on a cord, with my father, the device simply hanging around his neck. In the evening he simply puts it in the supplied charging cradle, which is readily available on the bedside table with him. So just practice and to extremely inexpensive. The mobile phone is a certain security that appreciate even my father with his 85 years.
