... now they recommend the ONN Android streaming pucks from Walmart instead...
I had one of those for a while, it didn't play nice with my home theater system. When switching apps, or whenever it feels like it, the Onn box, receiver and TV got into some sort of 3-way shit show over some or another HDMI parameter, resulting in the screen flashing between black, pixelated green and an annoying loading spinner, and the receiver clicking audio relays and generally having a fit. Got a 4K fire stick too, and that works fine, as does the little x86 SBC I'm currently using.
Another annoying feature of the Onn box is, it likes to update itself automatically even if you turn that off. And one of those updates broke it such that when it's idle for a while, it turns itself "off" and doesn't draw any less power, but takes a while to turn back "on." Before I got rid of it, I had a Home Assistant automation to send it a new "on" command every time it turned off.
I suppose Amazon might eventually get around my pihole whitelist and fuck up my fire stick, in which case I suppose I'll do their "trade in" thing for a new one then return it.
