I was hesitant to get one of these devices, but I can say it's actually been nice. Two issues so far.
1. the speaker sometimes starts to crackle. restarting the unit fixes it. May need to replace this one. 2. I found a setting to stop amazon from using my recordings to "improve" Alexa. When you turn it off, it warns you that your device won't work as well, and it seems to be true. This doesn't seem to be very ethical of them to prevent the unit from working at peak performance unless you sacrifice privacy.
5 stars if these items were fixed. Far more useful than I had expected it to be.
