I got it on sale for 3k. For the price, it offers decent sound and richer bass, compared to my much cheaper, 1.5k Bluetooth speaker, the Boat Stone 260. It works seemlessly with my smart home devices, and the app is fantastic. It yet doesn't have support with fire TV stick, but Amazon assures it'll arrive by mid-november, so that's something to look out for. The app works great, and you can control your smart home or this dot from anywhere in the world, as long both of your devices have an internet connection. It's a fun little party trick, really. I couldn't be more happier with my echo dot. Also, as you can see in the picture, I got the sophisticated looking white color ;)
Edit: It has fire TV support now, it's not the best experience, but hey - it WORKS.
