We have two different dots under two different accounts. One is mine and the other belongs to my grandson. He has to be careful when talking to his that his door's closed. I tried to get him to change his Alexa to echo , but he wouldn't do it . Of course I'm not changing mine because I'm used to the original name for the one I have at my mother's.
Right now, I have no plans to get any of the other add-ons. I'm happy with her the way she is.
