I set mine up, and they work great. I'll be using mine with external speakers/amps, but the internal volume is sufficient for basic interaction. Of course the fidelity is pretty poor with the internal speaker, but that's to be expected.
I noticed that during setup it asked if the device would be used standalone or with external audio. Anyone know why the question? It works with either no matter how you answer. I don't know if it might change how it processes mic input, or if it was just a survey type question. I don't see anything in the interface to change that "setting" though, if it is a setting.
In any case, these will be a nice compliment to my main Echo. I've been lamenting the lack of an Echo in my basement office
