It all depends on how you are going to use it.
For local playback from a USB flash drive or even HDD then for many things up to 1080p and even some 4K it will work adequately.
But with S912 and S905X2/X3 boxes that can be had for not much more, even if today,$15-$20 is all you have, I would save up for just a little longer and get a far better and faster box.
If using your network to stream, then dual band WiFi and/or Gigabit ethernet will be of great benefit.
And in even the short/medium term, you will likely regret buying such a box unless the outlay is such that you can consider it throw away money in order to try something out for the first time.
I guess the only other potential practical use could be as a headless host for a TV tuner but even then, it’s not that desirable.
In terms of getting advice and guidance on the latest TV boxes, apart from this forum of course, Freaktab is generally considered the best source of guidance where there is great discussion and testing carried out.
Or if you like to see Youtube reviews, I would recommend the excellent ETA Prime channel,where there are always a great range of boxes and boards reviewed.
Personally I would avoid it as despite what may be seen as great value, is more a case of getting rid old stock of what has been a largely failed attempt at a cheap AMLogic SOC that has now been superceded (price wise) by better and cheaper older SOC’s and (technologically speaking) a couple of new ones.
