I ordered one of these alarms for my mother and, from the initial internet search to delivery and installation, we received excellent service. It arrived the day after I ordered it! The instructions were clear and easy to follow and there was first class support during the testing process. It is helpful that there is an option of necklace and bracelet version, and the fact that this device has a range of 100m and can be worn in the shower, are added benefits. It has given both me and my mother great peace of mind, knowing that someone can help if she has an accident.
