TLDR version: Yes - generally VERY well, and was definately worth the money paid.
Longer version:
It's not perfect; and it can struggle with some Youtube 1080p60 content due to the video conversion overhead, and the same goes for the new 1080p60 system wide refresh rate they added to the settings, albeit if you were willing to reduce its output quality in the system settings it might be useable, but at its default essentially 1080p30 display output, it'll play most streaming services pretty damn well with low audio latency; which is exactly what I wanted.
I cannot get Xbox Gamepass Streaming working on it (it loads, plays the Xbox logo, then goes to black screen before going back to the menu 10-20 seconds later as though its failed to negotiate the stream video), albeit it will happily accept bluetooth peripherals, I am suspecting its a conflict between the streaming requiring full 1080 output for most games, and the display apperture in my car is limited to ~1920x980 or similar due to my car's OS, certain apps dont work/display properly due to I guess a missing framework and Whatsapp didn't work until after a firmware update and me setting the display mode to basically zero scaling (I'm not sure if the firmware or the display setting changed fixed it, but it works now), but it's had 2 firmware updates this year already, and the support does respond, and will try to help.
Example of this is I requested the optional remote included with mine; mine arrived and unfortunately had a fault, so they sent me another aftermarket remote at thier cost which arrived a few weeks later; something I had to admit I was initially sceptical about.
I cant promise they'll continue to release firmware improvements, but it is at least a positive sign they have released some - more than I was expecting for a Chinese solution given how many of them are basically WYSIWYG.
They also worked with me on another physical issue, to reasonable satisfaction.
As with a lot of US/Chinese stuff though, be aware if the unit develops a fault after the initial 30 days I believe, you will need to pay to ship it back to them for a replacement/refund.
Either way though, Prime Video, basic Chrome usage, Youtube, Crunchyroll, Disney+ etc all work great, and that's exactly what its used for.
For the money I paid I'm very happy; it's not perfect, and I wish it was a little more powerful/had 5G connectivity, but for my primary use case (which is letting my wife watch stuff whilst I'm on the move) or me when I'm waiting somewhere, it's excellent. They have a microSD slot too, I've not checked the full hardware accelerated video playback capabilities reported, but you could also easily load up media onto a card, and play it using VLC (which comes preinstalled) or another player of your choice, which as long as you chose a HARDWARE playback compatible file type (so as not to add unecessary load on the CPU) will likely run flawlessly - I keep thinking I'll need to test that at some point but never get round to it!
Stuck an 80GB a month Three data sim in it too (4G only - no 5G modem in this and most similar boxes), so between that and my mobile hotspot, I've basically nearly always got data from one of the two sources as well.
The only other caveat is occasionally the box stalls up a bit, but I just installed a google play programme which gives me access to the OS reboot functionality, and that always seems to do the trick. Its been less of a requirement on newer firmware too.
The box essentially cost me around £150 after all conversions and such, and given how much use its already had in the last 5 months, it was 100% worth it.
Nicely if I move it to another car, it also goes through a whole interface detection thing, so you never get caught out with it being usable on a car with a different resolution display.
The only MAJOR caveat is your car MUST support wired carplay to do the initial setup; its possible to change it to wired android auto after, but it defaults to utilising the carplay interface.
