The Eufy Genie boils down to this: it’s an Alexa speaker but not an Echo. That means that it’s basically a $35 product you can buy to talk to Alexa, order goods from Amazon, and listen to music.
That said, you miss out on other features that the Echo Dot offers, like calling other Echos (which I like). I also think it’s worth the extra $15 to buy an Echo that will continue to get updates from Amazon, and will sync with the Amazon app.
Final answer: Buy an Echo Dot instead.
