Been using it since it was Grandcentral. Have 2 of them. while its intended purpose would be great if your single, with moltiple lines i havent really found a way to use it as our Primary number. I actually got the origianl number because it was local to where all my family still lives in Indiana, none of my family has had a long distance charge calling us in a long long time. I also grabbed one when we moved to the toledo area because we kept our MI cell numbers for freinds and family to call us toll free, and this gave us a local number to give out instead of our cell numbers for people who still use those crazy things called landlines So in summary I use it for: Family to call us toll free, and avoid toll calls myself. Works great if you have a "my circle/fav 5/free incoming/freinds and family etc and can live without caller id...unlimited minutes to everyone!! School emergency number, rings every phone everywhere! Call my buddy in Canada Prank people with sms feature since not a whole lot of people know it, and its so easy to sms bomb people with a keyboard! Plus if its funny you have a log of it! give out to salesfolks so if its leaked it can be blocked. Voicemail Had some quality problems since the google takeover with the 419 number other number trouble free since the beginning
