The first 3 days o had the Alert 1, it activated 3 times. Once when I leaned against a cabinet (was wearing on my belt) and two other times when I would lean against or brush against something. Then I fell. It was a significant fall and I was injured. Then, the alert made no sound at all. Fortunately, my daughter was nearby and she helped me. When I reported this to your company, I was told I should not be wearing it on my belt. However YOU provided me with a belt attachment and told me to wear it this way. I have returned your equipment as I really do not want or need something that does not work.
