    Many Great uses, less than execution.

    Great addition to my smart home at first, set up was the right amount of tinkering for me. Issues arised when using the echo as assist device over long term. The device seems to freeze up after a while, probably needing to restart, but the issue progressed until it would need to restart between each use. The mic worked suprisingly good, not flawless, but great for the price. The speaker is not great, but it's like 1 cm so So that's to be expected. I'm sure I'll have some use for it in my smart home though and while it didn't live up to my plans, there's a high likelihood it's due to my limited knowlesge and imagination. I am happy with my purchase, but would gladly pay more for a more robust device that wouldn't need external speakers or mics and that remains consistent executing functions.

    Delivered on time, and responded to my email

    Was afraid I put in a double order, customer service was great, they checked and confirmed, I ordered 1 time. After that, I got a timeline for delivery and am completely satisfied with my purchase.

    good for fun but that is all...

    Not usable in home automation: device goes in idle mode at random moments + speaker is barely audible.

    Does not work :(

    Unfortunately it does not work with home assistant

    Good proof of concept

    Not sensitive enough to be actually useful, in order to have it work as a microphone you have to have it in a near silent room and be directly in front of it. I'm using this with home assistant
