Xiaomi TV Stick 4k. I got an Amazon Fire TV stick, hated it very much, but luckily for me it malfunctioned after a month, and i managed to get a "refund" that was limited to the amazon store. I spent the money on the xiaomi alternative that came with android tv, as it was about the same price, but you can install (and keep installed) a custom loader without ads, and never have to update anything it if you don't want it. But be careful, some newer models from xiaomi come with google tv instead, which is probably harder to have control over privacy/ads.
