Emergency response time excellent, time for tech support the opposite. The knowledge of the Samsung Smart watch, with the exception, of pushing the emergency button, is horrible, This is not the Samsung S3, does not work the same. nothing online and to keep experimenting without initiating an emergency call is to say the least annoying. If you want the features of the Samsung watch buy the watch,if you need an emergency call button get an emergency call button, This watch is a hybrid, akin to the mule the mating of a donkey and a horse, in this mating neither donor was an ass but you wound up with one.
