The Echo Wall Clock was first announced by Amazon in September and started shipping just before the holidays in December. Just over a month after the clock was first made available to buy, Amazon decided to pull it because of problems with Bluetooth connectivity. That feature is essential to the device's function, as it needs to connect to another Echo device in order to operate with voice controls. With the fix, users will once again be able to set alarms and timers via Alexa that will be displayed on the 60 LED lights around the edge of the clock's face.
