Bests & Worsts Reviews from Amazon

While using the Echo to play audible books the Echo stopped working then would only play 2 words then quit. After contacting support i was told that he guessed the memory cache was full. My question is why and how did it fill and why is the memory cache not releasing no longer used memory? the answer i received was I don't know. I couldn't get a guarantee that it wouldn't happen again. I'm now returning this for a refurbished Gen 1 Echo. I've never had to go backwards in the world of technology in my life. Amazon, this product is an obvious money grab you should be ashamed. End users, DO NOT BUY THIS PRODUCT YOU WILL BE DISAPPOINTED. ***Update*** After using the product and comparing it to the generation 1 version and the Google Home. I would have to say that this 2nd generation is a downgrade and not really worth it. I don't know if it's still learning speach but it has serious issues when telling it to play music or audio books. Even when telling Alexa to turn off certain Hue lights she will occasionally tell me that the room i specified doesn't exist and she repeats the room name, i will then follow up with the exact same command and it works. The sound is no where near what the Gen 1 was capable of. The only advantage i would give it over the 1st gen, thats no longer available, is changable covers. If you looking for Alexa and a decent speaker, this is not it. It may cost a bit more but an Echo Dot connected to your speaker of choice would be a better idea. This part is specifically for Amazon to address if they can or will. What exactly was upgraded from Gen 1 to 2? The mic's don't work as well and the sound quality is awful. What was upgraded? - Almost forgot, i called support for 30 minutes thinking the woofer was not functioning. FYI there is NO diagnostic tool of any kind to tell if the mics and speakers are working correctly, you just have to assume.
