Bests & Worsts Reviews from Amazon

This is one of the most infuriating purchases I have made. I recently bought a echo dot 3rd generation on prime day special but couldn't help wonder if the sound quality was different. The 4th generation device's sound is much better. It is a clear and less muffled. Which is great if I didn't need to connect it to anything or what to use any Alexa features. I've spent 4 hours going through every troubleshoot information I can find and no matter what this thing will not connect to my mobile hotspot wifi. I had some similar issues with the 3rd generation but it just took a few extra tries. I even tried to get assistance and they sent me the instructions already included then switched me over to someone else who wanted to start me over again with the same basic help links. This is infuriating because not only does this item not work as its supposed to but I also returned my functional 3rd generation which is now double the price and unavailable.
