I have had this for a little over two weeks now and so far I have had average experience with its responsiveness and operation. AS for set up, it was pretty easy and straight forward, just make sure you restart your phone and turn on Bluetooth and see that it has paired with your car already before attempting to plug in the Echo Auto and setting it up with your phone. The package comes with a vent install clip and a dual USB power adapter which is nice for some cars. I have a flat dashboard so did not use the clip and just used a double sided tape to stick the Echo to the dashboard and run the power cord along side to the power source. I think this would be a great addition to my smart devices if functioned as expected and currently I am not very impressed with it as far as the responsiveness as you have to wait several seconds from the time you call it out to wake and the time you ask your question or give it directions (unlike my other Echo devices) but will definitely try it out more and update my review as time goes by.
