Amazon just added another model to its increasingly crowded selection of living room offerings. There’s bound to be some consumer confusion around the line, but the Cube differentiates itself by bridging the gap between Fire TV and Echo. Sure, past set top offerings have incorporated Alexa control, but this latest addition folds in the full smart speaker experience.

In fact, the Cube looks like a big, square Echo Dot. It’s not much to look at, honestly, but the familiar design elements are all there, including the four Echo buttons on top and a glowing blue light that lets you know when Alexa is listening.
