Amazon’s family of Echo speakers are some of the most popular gifts right now, so many people are activating their Echo units for the first time.

Here’s what you need to know: These speakers, which can respond to either “Alexa,” “Amazon,” or even “Computer” (for those “Star Trek” fans out there), are extremely quick to respond, and understand your commands far better than any other device I’ve used.

Thanks to its excellent audio system, with seven microphones for listening and a 360º omni-directional audio grille for speaking, Amazon Echo works exceedingly well wherever I am in my home. I can hear it — and it can hear me — almost perfectly.

Amazon Echo has completely transformed the way I live in my apartment. There’s just so much you can do with Echo. Take a look.
