Steam controller review:
Pros:
- You can use it as a mouse/keyboard
- It has extra triggers on the bottom
- Wifi or wired. Wired connection does not need wires
Cons:
- Too big. Hands start paining after prolonged use
- Buttons are too close together. Too easy to "fat finger" unwanted inputs
- Need to add games to your steam library to get it to work with them (OS
does not see it as a gamepad)
Overall, I would choose a wired Xbox controller or PS4 controller over the
Steam one
