Ive used a fire stick and I wouldn't recommend it to anyone.
I used a Fire Stick as my main device for almost a year. It's a tad slow to boot up everything but once it does, it's fine. I'd recommend one to anyone to start with (of course it's a lot more useful if you are into the Prime thing). Once you've used a Fire Box you can't really go back, but otherwise, it's more than serviceable And that was before they updated it with the quad core processor (haven't used the latest version).
