I bought a Fire Stick on a day trip across the border because it was thirty dollars cheaper, and it worked perfectly except for two things nobody mentions when you do that.
The first is that it comes set up for a different region. Not in a way that stops anything working — it just defaults to American content, American time zone, and an app store that shows you things you cannot get here. Changing the region in the settings sorted most of it in about a minute.
The second was the power adapter, which was fine, and the plug, which was also fine because it is the same shape. So that was a non-issue and I had worried about it for the entire drive home.
What actually mattered, and what I did not anticipate, was the remote's voice button. It is tied to the account region, and for the first month it kept trying to search American services I do not have. Turning that off entirely made the thing more useful, not less.
Once past that, the setup was ordinary. Install the player, enter the details, let the guide populate, spend twenty minutes on favourites. The stick itself does not care which side of the border it is on.
One thing I would say: if you are buying one here rather than bringing it back, the price difference is smaller than it used to be and you avoid the region faff entirely. Thirty dollars was not worth the two evenings I spent on it, and I say that as someone who enjoys this sort of thing.
The other point worth knowing is that the stick's own wifi is the weak part regardless of where you bought it. An ethernet adapter is about twenty dollars and it is the single best thing you can add to one.
The walkthrough I followed for getting it running properly, including the settings that are not where you would look, is here.
Thirty dollars saved, two evenings spent. I would buy it here next time.
