The Prime Day deals on Amazon devices are stacking up, and one of the best is on the Echo Dot Max, the company's newest Alexa+ AI smart speaker. It's currently at its lowest price ever—64.99, a 35% discount from the $99.99 list price. If you’re looking to upgrade from an older Echo Dot or bolster your smart home with a gadget that combines several accessories at once, this is a deal worth considering.

The Echo Dot Max is a versatile jack-of-all-trades, functioning as a smart speaker, voice assistant, smart home controller, and mesh Wi-Fi extender. If you’re building a smart home from scratch, it’s a helpful device to simplify your setup, reducing the need to separate hubs and accessories. It includes everything you’d expect from an Echo device, including voice control, music streaming, weather updates, built-in motion and temperature sensing, and hands-free smart home management. It supports Alexa+, Amazon's own ChatGPT-esque chatbot (access is free for Prime members). 

The speaker delivers strong sound with a small footprint and supports Matter, Thread, and Zigbee devices. While it does offer more flexibility than similarly priced Bluetooth speakers, if your main goal is to upgrade your audio setup, there are stronger options on the market from brands like JBL. As is typical of many Amazon devices, much of the value of the Echo Dot Max comes through its integration with the rest of the Amazon ecosystem—but it's a capable AI-enabled smart speaker in its own right.
