Easy to set up for just the counties and alerts that you want. Note: it will alert you with sound day and night so make sure you only set the alerts for the most important ones so you won't be woke up at 3am for a storm "watch", etc. or a flood warning, if you don't live in a flood zone, etc. All in all, great item for the money and with all the tornadoes this country has had this year, I feel safer with it. We had a tornado warning right after buying this and since we don't have tv on local channels this helped us get to the basement in a timely manner.
