I own both an echo and fire tv stick with alexa support.
I will focus on the echo and it's setup process, since the fire tv stick comes set up with alexa when you buy it.
As for echo setup, it's rellatively simple. You plug it into the wall and wait for the nice chimey logo to tell you it's on. She'll then tell you to open the alexa app on your phone of choice, and setup a new device.
Setting up a new device couldn't be simpler. I have gone through this on both IOS and android. IOS seems to have a smoother time of it, but the android app isn't bad either.
You'll go through some obligatory screens. I'm not entirely sure now, but I think the only thing you have to do is connect to the echo personal network in phone settings, then find a wifi network for it to connect to. Voila! You have a fully working echo. I usually ask mine the time to confirm this.
As for skills, I highly recommend going through and taking a look at what you can find. There are a lot. The accessibility of this is good, fantastic even, so there should be little problem.
Things to note, however.
If you use/subscribe to tunein premium, it won't work on the echo. Don't even bother. We've been getting on them to fix this but they don't seem to care so much.
If you haven't got amazon music but you do have spotify, you'll have to change your default within the app. Otherwise, you'll be stuck saying play X from spotify all the time.
Hope this helps!
