Simply put wow! I love Alexa and all the fun things it does but one thing that had me disappointed was the lack of portability in all the echo line. Also the echo dot just sounds bad and listening to music on it is quite lackluster. This completely solves all the problems with the echo dot. Sound is amazing! Battery life is as advertised and will not disappoint. The build quality is very nice and does not feel cheap at all when held and touched. You can still see the cool light ring on the echo and it fits in it perfectly(like really perfect,no jiggling or gaps). I also found that voice activation of the echo to be more reliable while playing loud music and I no longer have to scream at Alexa to get her attention. I figure this is because the speaker part is further from the microphone part. This product makes the echo dot 2nd gen fun to use again.
