Bests & Worsts Reviews from Amazon

While it might seem trivial, before today the Echo was the hub of my home automation which I loved to demonstrate to my family and friends. Today Amazon remotely updated my Echo and removed the voice response to commands of 'okay' and replaced it with differing tones each with a different meaning. ! This device is no longer cool, and has lost the interactive 'human-like' touch of a verbal response. Amazon should return the voice response or at least make it an option. No notification of the update was received. I really feel like I paid too much for this device after this change.
