Amazon Echo Dot (2020) review: Well-rounded in every sense

Amazon's smallest Echo has evolved quite a bit over the years. The first Amazon Echo Dot was small and puck-like but didn't have very good audio. In 2018, the company upgraded the Dot's speakers to a new 1.6-inch driver that gave it a lot more bass and overall better performance, plus it had a much more stylish fabric-clad exterior. Last year, Amazon added a new model called the Echo Dot with Clock, which is basically the same thing but with a digital clock on the front. In 2020, however, the company has decided to go… round.
