Amazon 2nd Gen Echo Dot review

Amazon'sEcho Dot: Still a crown jewel of the modern smart home

Summary

The Dot is a smaller yet just as powerful version of the Amazon Echo. What it lacks in an internal speaker system it makes up for with an audio-out port and Bluetooth connectivity. While the app and inability to route queries to a single Alexa device within close proximity of each other can be annoying, the $50 price and Alexa's usefulness make the Dot a solid option for anyone who wants to start building a connected home on the cheap.

Hardware

At only 1.3 inches tall, the Dot (available in black or white) virtually disappears into your home. It can be placed anywhere, and it won't disrupt your carefully decorated room. Like the larger Echo, the second-generation Dot can be used to fill an Amazon cart. But that's not the only thing people use it for. Instead, the Alexa platform is an incredibly helpful connected home hub, a fountain of random facts, an audiobook reader and a music player.
Indeed, it's music where the Dot really shines, thanks to an audio-out port and Bluetooth speaker support. That gives it access to nearly any audio system in your home. The full-size Echo's built-in speakers sound fine too, but the stereo system I already own sounds better.

Also, you can switch between wired and Bluetooth speakers on the fly by enabling and disabling the Bluetooth connection with your voice. That feature allowed me to switch my audio source in two different rooms using a single Dot. That said, the Alexa platform does work with Sonos if you want that type of audio system and you have the money. Unfortunately, you can't play audio out of both a wired and a Bluetooth source at the same time. Like the Echo, the Dot has an internal speaker, but it's too anemic for audio playback to be truly enjoyable.

And while about 90 percent of your interactions with the digital assistant will be voice-based, there are physical buttons on top of the device as well. The most important of those is Microphone Off, which, as you'd expect, stops the device from listening for the "Alexa" wake word. It's a great feature for when you want to discuss sensitive topics and you're feeling a bit paranoid. Indeed, there's good reason for being cautious with sensitive material: Sometimes the Dot and Echo think they hear "Alexa," even when that's not what you said. Now a bit of your conversation has been recorded as a query, sent to Amazon's servers and also stored in the app.

Additionally there are volume buttons that replace the full-size Echo's twistable top. Fans of the knob will be disappointed, but most of the time I use my voice to raise and lower the volume anyway. The buttons are surrounded by an LED ring that indicates when the Dot is listening and thinking. It also reflects the current speaker volume. It's a nice indicator that your assistant is listening, and it can be seen from across the room without being too bright or blinding.

In use

The thousands of "Skills" (what Amazon calls third-party add-on features for the Alexa platform) are where Amazon has a distinct advantage over Google's forthcoming speaker hub, called the Home. It already supports popular connected-home brands such as Nest, SmartThings, Philips Hue and IFTTT, as well as platforms from WeMo, Insteon, Lutron, Honeywell and Ecobee, among others. Plus it works with travel and recipe apps. You can order a pizza, flowers and a car with it. You can check bank balances and get news briefings from NPR, Fox and the AP. You can hear sports scores from ESPN, and you can even figure out how much gas is in your car using the "Automatic" Skill.

I tried nearly all of these (except ordering pizza, because ew, Dominos) and they all worked like a charm. But the Skills library -- like all app stores -- is filled with some add-ons that are better left ignored. For example, the Moon Age add-on notes, "you can know the moon age by asking to [sic] Echo." What does that even mean?

Adding all these Skills requires using the Alexa app, which is clearly the weak link of Amazon's platform. I've been using an Echo for more than a year, and in the past few months the app, frankly, has been a pain to use. The issue is that it says it's not connected to the internet, even when my phone and Echo speaker both can access the network without a problem. If it doesn't think it's online, the app becomes worthless. Fortunately, you can also tap into Alexa via your web browser. That workaround has consistently worked for me. But I usually learn of a new Skill while on the go, and if 20 percent of the time I can't add it because the app is buggy, that's frustrating.
Another confounding thing is that you can't really have two Alexas in adjoining rooms. Amazon says that its Echo Spatial Perception feature (ESP) determines which device hears you the best and sends answers only to that piece of hardware. But during my tests, the Dot and the Echo both replied and answered when I said the wake word or made a query. Even if I was sitting in front of one of them, if the other assistant heard me, it would react. To combat this, I changed the wake word on one device to "Echo." Those in larger houses with more rooms might have a different experience altogether, though.

The competition

While there are rumors of an Apple device on the horizon, the only real challenge to Alexa's dominance in this field is the forthcoming Google Home. While the Home does have some Internet of Things capabilities, they pale in comparison with the Echo and the Dot. While the Google offering works with four connected home platforms, Alexa supports more than 13 different manufacturers and developers. But the $129 device will allow for audiocasting to multiple devices that support Google's audio and video streaming service. The Dot, meanwhile, can send music only to a single device.

So should you buy it? Yeah, I think you should, though the Home Mini is probably the better choice for anyone who's already invested in Google's ecosystem. All the same, the Echo Dot is delightful, it's cutting edge and, even going on two years into its lifespan, it's as good a value as you're likely to ever see in tech. AI will undoubtedly play a growing role in our lives and, yes, in our homes, and that makes the Echo Dot the most accessible glimpse of what's next that we've currently got.
