Life Alert ads are all over the place, but I don't think they offer the best medical alert system anymore (if they ever did). Don't get me wrong, Life Alert isn't bad but when I was doing research on medical alert systems for an elderly uncle, I found that there are a bunch of new technologies that are probably a lot better. Everything from cell phones with emergency alerts (cell phones can be better than these pendants because they work outside of the home) to medical alert pendants with fall detection. I'd look for more options before buying Life Alert.
