Amazon's Echo Dot is a great way to bring Alexa to more rooms

Setting up the Echo Dot is only slightly more involved than with its larger sibling, mainly because you have to plug in an auxiliary cable, in addition to a power cord. You'll have to use Amazon's Alexa iOS or Android app to get the Echo Dot connected to WiFi, which typically only takes a few minutes. The Alexa app is also where you can manage the Echo Dot's settings, as well as its "skills," or connections to third-party services. You can also go through voice training with the app to help your Echo Dot understand you better. The Dot feels like a large hockey puck: It's basically the top part of the original Echo sitting on its own.
