It's cheaper than Echo dot, The sound quality is a little better, The far-field voice processor works fine in a quiet room but you have to yell at the thing if your playing music on it to stop it. I did notice when you ask it something there is about a 20 second delay before it responds but when you tell it to turn on a smart plug it does it right away, I found that a little odd. But overall it's pretty cool for what it cost.
Comes with US adaptor, wouldn't set up plugged into PC for power. Can't change wake up word from Alexa. Bit harder to talk to than the Dot, needs a silent room where the Dot seems not to mind the TV in the background and a little slower to reply, but it is cheaper!
Great if you've had no experience of an Echo Dot, but a little disappointing other
