The newest generation of Amazon's Echo Dot has a version that comes with a neat digital clock on an LED display. The display even adjusts its own brightness, using a light sensor, for visibility during day or night. Like other Echo devices, it can still play music, make calls, or give users the news. Compatible services include Amazon Music, Apple Music, Pandora, Spotify, Audible, and iHeartRadio. Users can also pair the Echo Dot with an Amazon Fire TV to voice-control their movies! Enabling Alexa Guard allows the device to alert users when it detects smoke alarms and other home concerns. With countless "skills", Alexa's capabilities keep rising for convenience and utility. The device measures 3.9" x 3.9" x 1.7" and weighs 10.6 ounces. It also comes with a 3.5mm stereo audio output for external speaker connectivity.
