It's a $30 Android box with 16GB storage and 2GB RAM.
It's probably sufficient initially, but likely quite slow. In the long run you'll see no support or updates at all.
Depending on what you're looking for, a FireStick or Roku is probably 'better' for the apps it supports.
If you want AndroidTV, there's a bit gap between 'cheap' (<$50) and 'supported' over the long run (something like an
Nvidia Shield @ ~$150).
If you really wanted to go with a cheap Android box, I'd suggest shooting for at least 32GB / 4GB and Android 10. You'll never see support or updates, but at least it should be usable for a while.
