It's surprising that it took Echo Dot smart speaker this long to start looking like, well, a dot. The fourth-generation Echo Dot is now a sphere, to mirror the look of the new fourth-gen Echo, albeit in a smaller size for half the price. Not much else has changed here, but the new Echo Dot remains one of the best ways to add Amazon's Alexa voice assistant to every room of your home. That said, we think the LED clock face on the Echo Dot With Clock is worth the extra $10 if you plan on putting the speaker on your desk, nightstand, or anywhere else you use clocks and timers.
