Well - - it was a nightmare to set up, about 2 hours, and about an hour with on-line chat to Amazon
I've had no problems with the previous 3, and this one went well re setting up the router password etc (using the app I already had on the ipad)
Then it said it was going to play a short video about how to use it, at which point the app froze, and I couldn't get out of it.
Eventually (on chat) I had to delete the existing app, then download it again.
Even then, it got itself into a loop, just going back and forth from one page to the next and back again, forever.
All I wanted to do was change the wake-up word to Echo, but the app wouldn't even let me do that.
Chatman said I could do it by speaking to it, but that wouldn't work either.
Then I was told to log in to my account on the PC, this had lots of problems as well.
Eventually I did it, but not even sure how.
And there is no telephone number I could find for CS, the the chatman wouldn't give me one, but left a message for them to ring me. This was about an hour ago, no call yet.
The chatman's name was Marvin, but I didn't ask him about his magic set which QVC sell !
Now it is working, it is VERY loud, and has good bass and treble, perhaps a bit lacking in the mid-range.
