The Amazon Echo Dot is now on its 3rd rendering. The Dot is the most popular of all the Amazon smart speaker devices currently available.
The 3rd generation now comes with a fabric design and moves away from the plastically feel of the earlier models. More importantly the speaker is improved and so the Echo delivers a better quality sound.
Like all Alexa based devices you can use your Amazon Echo Dot to stream music from Amazon Music, Apple Music, Spotify, TuneIn and others. Listen to audiobook from Audible. What do you do with your Echo? At the moment I am enjoying using my Amazon Echo to listen to international radio stations via TuneIn.
