Great sound, decent amount of features and does what I need it to do most of the time. However, the rest of the time it is plagued with bugs and glitches. It will often get stuck playing the same playlist in the music skills, I have constant issues with drop in not being able to heard on a second echo device. Have to constantly restart the devices.
Seriously thought it would be a much better user experience, but sadly Amazon have a long way to go yet.
