Amazon Echo Dot (4th gen) review: Alexa’s new small budget ball

Smart speaker ditches puck shape but keeps solid sound and function with or without LED clock display

Amazon's fourth-generation Echo Dot has evolved from its predecessors' puck-like appearance into a small ball, shaking up the idea of what a small smart speaker can look like.

The new Echo Dot is priced the same as the last one, costing from 50, although it will be frequently available at a discount at various retailers, and looks like the full-sized 80 Echo hit with a shrink ray.
