Do you have any extra console controllers? Xbox 360 controllers work great.

I have 2 of these, no issues, seem to work well. https://www.amazon.com/gp/product/B01EO5QPN2/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1

For playing games? In the review I read the reviewer said something about the Mi Box hardware seeming to struggle mightily with very basic games.

I bought the Mi gamepad for $20 and it works great.

What about just using your smartphone?

If you want quality for a reasonable price, the GameSir G3s is what you're looking for.

Waaay better than the Matricom models in both the shoulder buttons & analog stick quality/feel, comparing them side-by-side, being that I own both.
