I have 2 echo show 8's with power blocks. Both work fine. I used them to communicate with my aged parent but they have lost the ability to use it. I have a gen 1 and a gen 2 (gen 2 has the square camera). Gen 2 is $80, gen 1 is $70. Gen 1 has a scratch on the screen, but it does not affect operation. Cash only, no holds.
