I have been using the unit for approx a month now and like it. As my Nissan only has Bluetooth phone and not audio, it is connected to the AUX IN jack. Sound and volume work fine and use it frequently. Data streaming from my cell appears to be reasonable despite constant use. As an early adopter of the Amazon Echo for a few years now with several units, I find the Apple App to be a little clumsy. The greatest suggestion I would offer to Amazon is to allow for custom device names rather than the 3 or 4 offered. It has now become dangerous to use "Alexa" as a call name as I noticed on one of my units, it was activated by TV or radio shows quite easily.
