Amazon Echo 4th gen speaker


Hello list
I hope this is not off topic. Here in SA a company advertise an amazon echo
4th gen with smart hub included. I searched on the amazon site for such a
device in the hope I can find a book explaining the device but I do not find
the device. Is there such a device? I specifically look for an echo with a
smart hub. Also, is there an email list for echo devices?
